I didn't try to figure out why the code in libgcc/config/m68k/linux-atomic.c is
causing the GCC 4.7.1 xgcc cross compiler to fail.  I just patched
libgcc/config.host to disable atomic builtins when compiling for Motorola
m68k/ColdFire running uClinux with uClibc:

Someone still needs to figure out why the implementation fails for m68k-uclinux
