One minor comment -- specifying CFLAGS symbols and LDFLAGS libraries not
*required* by what you're compiling may possibly produce undesired results.

I try to restrict my own /etc/profile to truly global things that need to apply
to EVERYTHING I do in POSIX.  My own observation is that CFLAGS/LDFLAGS tends
to be too program-specific to be specified globally in /etc/profile.  Better to
specify this stuff either in a Makefile or in a configure script wrapper.
