Revert "kbuild: make better section mismatch reports on i386, arm and mips"
This reverts commit f892b7d480eec809a5dfbd6e65742b3f3155e50e, which
totally broke the build on x86 with CONFIG_RELOCATABLE (which, as far as
I can tell, is the only case where it should even matter!) due to a
SIGSEGV in modpost.
