It's broken too many of my recent builds.  We can add it back in when
things stabilize or perhaps after we get it to swig with a recent
version of swig that we can make part of the clean bootstrap/build
process.

POSIX sed doesn't support grouping, so split the regex in two.

Speculative fix for a mod_python build issue on OSX, which is
caused by '-arch i386 -arch x86_64' in the final PYTHON_CFLAGS.

Filter both flags and hope OSX's universal binary toolchain is smart enough
to choose a sane default.

Our default build probably shouldn't include non-free software.  With
mod_ilbc, the licensing situation is merely ambiguous.  With
mod_siren, the user can't use this code without getting explicit
permission from Polycom (though it is apparently easily given).

The test was backward.  If the revision is in switch_version.h.in then
we have the version already.
