I think that should work but my setup is broken somehow: it can't
find the 32 bit libgcc (and in passing finds and discards the 64 bit
version):

cam-vm-266:precise:tcg$ make linux-test
ccache gcc -m32 -Wall -O2 -g -fno-strict-aliasing  -o linux-test
linux-test.c -lm
/usr/bin/ld: skipping incompatible
/usr/lib/gcc/x86_64-linux-gnu/4.6/libgcc.a when searching for -lgcc
/usr/bin/ld: cannot find -lgcc
/usr/bin/ld: skipping incompatible
/usr/lib/gcc/x86_64-linux-gnu/4.6/libgcc_s.so when searching for
-lgcc_s
/usr/bin/ld: cannot find -lgcc_s
collect2: ld returned 1 exit status
make: *** [linux-test] Error 1

I have a feeling that precise's mostly-working multiarch support
may be the issue...
