Sprinkling the code with these #if clauses is ugly and prone to breakage I think.
The Makefile part is testing for the same feature.We do a very similar thing with -msym32, and KBUILD_SYM32. Perhaps you could rework this patch in a similar manner and test for KBUILD_MCOUNT_RA_ADDRESS instead of the '(__GNUC__ <= 4 && __GNUC_MINOR__ < 5)'
