Bugzilla Bug 106701

libgdiplus (x86 stable) failed to build; I mostly ignored the error, and tried
to emerge newer and newer versions.  They all fail on compilation of mmx code.

The option for using MMX code seems to be autodetected based on CFLAGS.  Using
my default of CFLAGS="-pipe -O2 -march=pentium-m -mfpmath=sse -funit-at-a-time
-finline-functions -ftracer" failed, but CFLAGS="-mcpu=i386" worked.

Reproducible: Always
Steps to Reproduce:
1. Set CFLAGS as above.
2. emerge
3. Watch failure.

( And if you want to do so...
 4. Set CFLAGS="-mcpu=i386"
 5. emerge
 6. Watch success.
)
Actual Results:

!!! If you need support, post the topmost build error, NOT this status message.

Expected Results:  
Emerge should succeed with my fairly conservative default CFLAGS.  If MMX code
is indeed broken (or broken on some platforms, even), it should be able to be
turned off somehow.
