Browse Source 
Add a patch to remove some stupid configure.ac that does completely
crazy things with the CFLAGS and CXXFLAGS leading to build failures
like:

Don't do horrible magic with CFLAGS and CXXFLAGS
The purpose of the lines being removed is to suppress the
-g<something> option from the CFLAGS or CXXFLAGS, when --enable-debug
is not used. This is stupid because it is up to the user to pass these
flags or not.
But it is not only stupid, but utterly broken: if your CFLAGS contains
a flags like -mfloat-gprs=double, then this option gets truncated to
-mfloat simply because the option contained the -g string!
Completely ridiculous piece of code, so get rid of it.
