Filter out -no-cpp-precomp from flags passed to SWIG.This is necessary since APR for whatever reason leaks the fact that it uses-no-cpp-precomp on OS X into apr-1-config. Unfortunately, a lot of versionsof APR have this in the wild so we just have to deal with it. If you use clangdirectly you don't see this because we already filter it out of CPPFLAGS.* Makefile.in (SWIG_CPPFLAGS): New variable, deliberately pulling in EXTRA_CPPFLAGS and not EXTRA_SIWG_CPPFLAGS because it would be harmful to split those (e.g. users wanting to enable a feature that adds an API).* build.conf (swig-python-opts, swig-perl-opts, swig-ruby-opts): Use SWIG_CPPFLAGS instead of CPPFLAGS.* configure.acc (SWIG_CPPFLAGS): Add the variable and copy it from the normal CPPFLAGS while filtering out the -no-cpp-precomp.
