What I am saying is that if 

src/s/gnu-linux.h 
would use $(CRT_DIR)
then src/m/amdx86-64.h would not need special casing for GNU_LINUX.

${canonical} should be sparc64-* for the 64 bit case, versul sparc-* for the 32 bit one.
Same for powerpc.
Alternatively, less clean, but maybe easier to do: the same trick used for
c_switch_machine could be used for LIB_STANDARD/START_FILES.
