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. Signed-off-by: John Crispin <john@phrozen.org>
