When building the synth target-side on a 64-bit box, this patch should
cause the build to default to gcc -m32. Provided the appropriate
32-bit development RPMs or equivalent are installed, the target-side
should then build happily.

* cdl/hal_synth_i386.cdl: when building on x86_64 machines, use
gcc -m32 instead of i686-pc-linux-gnu.
