Configure stage without a cache against a warm cache: mtools 3.34 s -> 0.28 s gengetopt 4.39 s -> 2.13 s fakeroot 10.97 s -> 8.73 s xz 4.32 s -> 2.17 s libressl 3.07 s -> 1.46 s flex 12.32 s -> 10.98 s expat 2.74 s -> 1.52 s bc 1.34 s -> 0.38 s dosfstools 3.13 s -> 2.54 s libtool 2.86 s -> 2.29 s mtd-utils 4.06 s -> 3.56 s flex, fakeroot, dosfstools and mtd-utils run autoreconf in the same stage, and the cache does not reach that part. Each of the eleven configures the same way with a warm cache as it does without one: the check configures three times, without a cache, with a cold cache and with a warm cache, and every generated file of the first and the last run is identical. A static scan of each configure script found no cache check that changes CFLAGS, CPPFLAGS, LDFLAGS or LIBS without restoring it. patchelf, mklibs and automake pass the same check but gain less than half a second, so they stay out. make world after make tools/clean now takes 121 s against 177 s with cold caches.
