 fftw-3 fails to configure for ppc64 with Macports gcc7 due to this
 problem: #64260

 I have now a working gcc10 outside of Macports, which can build binaries
 for ppc64. Set it as default gcc and tried to use:


 {{{
 36-111:~ svacchanda$ export CC=/opt/iains/powerpc-apple-
 darwin9/gcc-10-3-ppc/bin/gcc
 36-111:~ svacchanda$ export CXX=/opt/iains/powerpc-apple-
 darwin9/gcc-10-3-ppc/bin/g++
 36-111:~ svacchanda$ which gcc
 /opt/iains/powerpc-apple-darwin9/gcc-10-3-ppc/bin/gcc
 36-111:~ svacchanda$ sudo port -v install fftw-3 configure.compiler=gcc
 supported_archs="ppc ppc64" build_arch="ppc ppc64"
 }}}


 However it fails now with a different error:


 {{{

 Please attach the config.log so that we can see why that configure test
 failed.
