I'd suggest the following:
The lines that explicitally set 'CFLAGS', 'LDFLAGS', 'LIBS' (and
others?) are removed from all Makefiles.

If you want to override those variables for a make you can specify them on the command line

make CFLAGS="-O2 -mcpu=athlon-xp" CC=/opt/gcc-3.4.2/bin/gcc

I have been doing to to compile with different CFLAGS and different versions of gcc.

This will override the default CFLAGS settings from the Makefile. Saves having to edit anything. You can use this to override other variables set in the Makefile. CC CXX CFLAGS LDFLAGS prefix DESTDIR ROOT. Maybe not DESTDIR and ROOT with qemu but they are 2 other things that do get set this way with other projects.
