mod_wsgi @4.7.1 build failure: lipo aborts due to multiple input files with same arch

[khepler]

The mod_wsgi configure script appears to be adding its own -arch flag to CFLAGS. This results in passing two files with same arch to lipo which refuses to combine them.

fatal error: lipo: /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_www_mod_wsgi/mod_wsgi/work/.tmp/ccXsMfMP.out and opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_www_mod_wsgi/mod_wsgi/work/.tmp/ccOAdFUl.out have the same architectures (ppc7400) and can't be in the same fat output file
apxs:Error: Command failed with rc=65536

Build works fine after removing macports' -arch flags from CFLAGS and such. I don't know how to remove the configure script's -arch flags; the help text does not list a relevant option.

It is not clear if this is specific to ppc, but I don't see any reason it would be.
