libhib: fix build on PowerPC

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.
