[Bug target/34025] Warning when compiling with -m64 -ffast-math on Intel Darwin

["howarth at nitro dot med dot uc dot edu" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #11 from howarth at nitro dot med dot uc dot edu  2007-12-16 01:05 -------
For some reason the last change isn't forcing the MULTILIB_CFLAGS to actually
be used on the build lines for the objects added to EXTRA_MULTILIB_PARTS.

# Recursively invoke make in the GCC directory to build any
# startfiles (for now).  We must do this just once, passing
# it all the GCC_EXTRA_PARTS as simultaneous goal targets,
# so that rules which cannot execute simultaneously are properly
# serialized.  We indirect through T_TARGET in case any multilib
# directories contain an equals sign, to prevent make from
# interpreting any of the goals as variable assignments.
# We must use cd && make rather than make -C, or else the stage
# number will be embedded in debug information.
T=`${PWDCMD-pwd}`/ \
        && cd ../../.././gcc \
        && make
