[Gc] Build with -m32 on 64bits OSX

[Yi Lin]

Hi,

I am trying to build gc with -m32 flag under 64bits OSX. I use 
'CFLAGS=-m32 LDFLAGS=-m32 ./configure;make'. However, no error message, 
but no 'gc.a' was generated.

I noticed there were some complaints during building:
/opt/local/bin/ranlib: file: .libs/libgc.a(checksums.o) has no symbols
/opt/local/bin/ranlib: file: .libs/libgc.a(gc_dlopen.o) has no symbols
/opt/local/bin/ranlib: file: .libs/libgc.a(pcr_interface.o) has no symbols
/opt/local/bin/ranlib: file: .libs/libgc.a(real_malloc.o) has no symbols
/opt/local/bin/ranlib: file: .libs/libgc.a(specific.o) has no symbols
/opt/local/bin/ranlib: file: .libs/libgc.a(backgraph.o) has no symbols
/opt/local/bin/ranlib: file: .libs/libgc.a(pthread_stop_world.o) has no 
symbols

Can anyone give a hint?

I want to get a 32bits library so I can link it with my program (32 
bits). Thanks very much.
