libhib: fix build on PowerPC

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.
