Building the iMX53 kernel with current gcc 4.6-11.09 tip results in:

arch/arm/kernel/built-in.o: In function `armpmu_event_set_period':
io.c:(.text+0x7d3c): undefined reference to `__aeabi_lcmp'
io.c:(.text+0x7d74): undefined reference to `__aeabi_lcmp'

arch/arm/vfp/built-in.o: In function `vfp_compare.isra.1':
vfpdouble.c:(.text+0x30f0): undefined reference to `__aeabi_lcmp'
kernel/built-in.o: In function `update_min_vruntime':
crash_dump.c:(.text+0x1a4): undefined reference to `__aeabi_lcmp'
kernel/built-in.o:crash_dump.c:(.text+0x9d4): more undefined references to `__aeabi_lcmp' follow
make[1]: *** [.tmp_vmlinux1] Error 1

The same kernel compiles fine with the 4.6-11.08 toolchain, and compiled
with 4.6-11.09 tip from a couple of days ago (probably before the last
upstream merge).


Also affects other kernels (at least Snowball) - IMO this needs to be fixed before the release
