	Subject: Freebsd-7.4 + std gcc 4.2.1 fails to honour -march=i586

Summary:
  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
