[Bug driver/42520] New: lto1 does not see -march and -mtune options

For example, `gcc -march=pentium -flto -fuse-linker-plugin main.c' causes this:
/usr/local/libexec/gcc/i686-pc-linux-gnu/4.5.0/lto1 -quiet -dumpbase cc0AFVJ9
-mtune=generic -march=pentium4 -auxbase-strip /tmp/cc7X43Dc.lto.o
-fuse-linker-plugin -fresolution @/tmp/ccoGGiIc -o /tmp/ccCcL0Ff.s
"-mtune=generic -march=pentium4" appears because GCC (4.5.0 20091224) was
configured with "--with-arch=pentium4 --with-tune=generic" options.
