Not sure if that would help. After all, images are being built.
People just don't care enough to have a look.

FWIW, next-20140808 build results on my build/test farm:
	total: 132 pass: 120 fail: 12
Failed builds:
	frv:defconfig
	mips:nlm_xlp_defconfig
	openrisc:defconfig
	powerpc:allmodconfig (binutils 2.23 and 2.24)
	powerpc:mpc83xx_defconfig (ditto)
	powerpc:mpc85xx_defconfig (ditto)
	powerpc:mpc85xx_smp_defconfig (ditto)
	unicore32:defconfig

with qemu test runs failing for arm, mips, mips64, and ppc.

Which points to the next problem: I simply do not have the time to track down
all those failures, and I would guess neither do others who might be interested.
Geert is doing an excellent job trying to report and fix things, but quite frankly
sometimes one feels like Sisyphus trying to keep builds clean.
