[Bug target/34904] New: -march=native doesn't work with multiple input files

[hjl dot tools at gmail dot com]

bash-3.2$ /usr/gcc-4.3/bin/gcc -m32 -c y.i z.i  -march=core2 -mfpmath=sse 
bash-3.2$ /usr/gcc-4.3/bin/gcc -m32 -c y.i z.i  -march=native -mfpmath=sse 
z.i:1: warning: SSE instruction set disabled, using 387 arithmetics

The problem is gcc driver never passed the proper -march=xxx to
COLLECT_GCC_OPTIONS.
