If you want to change your compiler arguments, just set CFLAGS/CXXFLAGS.
Having Mesa have this separate variable is a great way to have your arguments
not thoroughly propagated to all compiler invocations.
---
I don't feel strongly about removing the variable from configure, just
as long as we don't have to propagate it into Makefiles. I use shared
configure args including CFLAGS and CXXFLAGS across many projects, so
I've never seen the use for this one, but if people really care to
keep it, we should just append it to CFLAGS/CXXFLAGS in configure.ac.
