I found a problem with CFLAGS += -march=i586 on an i686 linking
a crt.o for an i686, then not running on an i586, I suggested
maybe -march could be extended to also select seperate lib sub
directories to at least trigger a link failure, rather than a silent
apparent good compile of a bad binary.
Others on freebsd-hackers@ made various follow up.
People on freebsd-toolchain@ & freebsd-i386@ might have valuable
input ? Not wanting to split the thread between lists, or cross
post, More than this one) or lose people on freebsd-hackers@, Could
you please look at
