either setting in %build
%configure CC=%{_bindir}/gcc32
%{__make} CC=%{_bindir}/gcc32

or
export CC=%{_bindir}/gcc32

I get this during configure:

checking for i686-redhat-linux-gnu-gcc... /usr/bin/gcc32
checking for C compiler default output file name... configure: error:
C compiler cannot create executables
See `config.log' for more details.

In config.log I have:

Do I have also to change CFLAGS...?
