Description of problem:
pypy.spec currently filters our "standard" distro-wide CFLAGS, with this comment and code:

  # https://bugzilla.redhat.com/show_bug.cgi?id=588941#c18
  # The generated Makefile compiles the .c files into assembler (.s), rather
  # than direct to .o  It then post-processes this assembler to locate
  # garbage-collection roots (building .lbl.s and .gcmap files, and a
  # "gcmaptable.s").  (The modified .lbl.s files have extra code injected
  # within them).
  # Unfortunately, the code to do this:
  #   pypy-1.4/pypy/translator/c/gcc/trackgcroot.py
  # doesn't interract well with the results of using our standard build flags.
  # For now, filter our CFLAGS of everything that could be conflicting with
  # pypy.  Need to check these and reenable ones that are okay later.
  export CFLAGS=$(echo "$RPM_OPT_FLAGS" | sed -e 's/-Wp,-D_FORTIFY_SOURCE=2//' -e 's/-fexceptions//' -e 's/-fstack-protector//' -e 's/--param=ssp-buffer-size=4//' -e 's/-O2//' -e 's/-fasynchronous-unwind-tables//' -e 's/-march=i686//' -e 's/-mtune=atom//')

I'm filing this bug to track this TODO item.
