subdir calls diralias twice for every target of every build directory,
and diralias splits the path into words twice to find its last
component. This takes a quarter of the parse time of the main Makefile.
Use notdir, which returns the same last component. The rules do not
change.

subdir expands the recipe of every target of every build directory when
it creates the rules, although make runs only a few of them. The main
Makefile creates these rules on every make call, and a build calls it
several times in a row.
Put only a call of the recipe into the rules, so that make expands it
when the recipe runs. The commands do not change. The parse of the main
Makefile takes 0.10 s instead of 0.15 s, with 318 package directories.

The variants of a package are built one after the other in one recipe.
For packages with many variants, such as the boot loaders, this makes
the variants the longest chain of the package build, also if nothing
has to be done.
Add PKG_PARALLEL_VARIANTS. If a package sets it, every variant gets its
own make target with the dependencies of the package, and the package
target depends on these targets. A package must only set it if its
variants share no files outside of their build directories.

Commit 501123eb7a ("include/subdir: on build failure always print
error") passes $(2) instead of $(1) to ERROR for the builds of a build
type, such as host builds. subdir has no second parameter, so with
BUILD_LOG set a failed host build is written to logs/error.txt instead
of logs/package/error.txt, where the other errors of the subdir go.

stampfile assigns the clean rule of its stamp to <subdir>//clean with
:=, so every call replaces the one before. toolchain and tools define
a compile and a check stamp, and <subdir>/clean only removes the check
stamp. After "make toolchain/clean", the compile stamp is newer than the
toolchain sources, the next build takes the toolchain as built, and the
target build fails because the compiler is missing.
Append the clean rule instead, so that all stamps are removed.

Add support for compiling DTS for the selected target. This can be
useful for testing if the DTS correctly compile and doesn't produce any
error.
This adds a new make target. To compile only DTS use:
make target/linux/dtb

This allows a package to be rebuilt for all different VARIANTs.
To do so, set VARIANT=*.
The wpa-cli package is not getting built after changes made by
19aae94 [build: avoid rebuilds of unset VARIANT packages], because
wpa-cli is only built when compiling a variant that includes
supplicant support, and the first selected variant may not build it.

If a Makefile defines some packages with VARIANT set, and others without
it, the latter will be built once for every different VARIANT set, each
build trumping the previous one.
Avoid rebuilds by only building unnamed variant packages when the first
variant is built.

It is impossible to locate package that failed the build just from log
once more build is run in parallel (that is more than one make job). The
only way is to scout log files for failed package going back trough log.
This change makes it so error is printed for package that failed every
time.

Replace the GNU time program invocation with a simple Perl script reporting
the timing values. Since we require Perl anyway for the build system, we can
as well use that instead of requiring a random GNU utility rarely installed
by default.

Busybox time supports the GNU time '-f' syntax used by the build time
logging implemented in ff6e62b288, however the prerequisite check added
only works with GNU time installed as `time` or `gtime`.
As busybox is a multicall binary, the name of the symlink setup by
SetupHostCommand also must be changed from `gtime` to `time` to fix the
value of argv[0]. This causes a number of shells (including bash) to use
their builtin impelementation of time, so the sole invocation has been
changed to use `env time` to use the value found on the $PATH.

The idea is to easily get the list of packages taking the most time to build,
and see if we can improve them
v1: Use SetupHostCommand as recommended by John
v2: add space after 'time:', remove useless /usr/bin/time from SetupHostCommand

Calling the clean target removes all .ipk files and un-stages the
package. Add a new target just for clearing the build dir and call that
one instead of the full clean target

This is used to save space on buildbot instances.
If any part of a package needs to be rebuild, the whole package is
rebuilt from scratch. Stamp files are preserved to allow dependency

This is intended to be used for a wide array of package sanity checks.
The first check that is implemented is for the hash of downloaded files.
It checks:
- Missing hash
- Use of SHA256 instead of MD5
- dl/<file> hash not matching hash in makefile
- deprecated MD5SUM variable
The deprecated MD5SUM variable check is skipped for feeds/ until OpenWrt
is updated as well
