Using 

gcc -m32 \
    -o $RPM_BUILD_ROOT/usr/%{_lib}/xorg/modules/drivers/mga_hal_drv.so \
    -shared -nostdlib \
    .libs/mga_halmod.o .libs/clientlx.o HALlib/mgaHALlib.a \
    -Wl,-Bstatic -lgcc -Wl,-Bdynamic

instead works for me. Stolen from the output of make generated by old
Imakefile ...

Best regards,
