cross compiling on x86_64

[Philippe A.]

I have installed FC6 x86_64 on my new system. I would like to know how I can
compile a 32 bit freetype package. The following didn't work:

rpmbuild -bb freetype.spec -bb --target i386

It fails with these errors:

checking build system type... x86_64-redhat-linux-gnu
checking host system type... x86_64-redhat-linux-gnu
checking target system type... i386-redhat-linux-gnu
checking for x86_64-redhat-linux-gnu-gcc... no
checking for gcc... gcc
checking for C compiler default output file name... configure: error: C
compiler cannot create executables
See `config.log' for more details.
make: *** [setup] Error 77
error: Bad exit status from /var/tmp/rpm-tmp.65705 (%build)

Thanks.
