Hi,
http://llvm.org/docs/MakefileGuide.html says
Override Variables
=============Override variables can be used to override the default values
provided
by the LLVM makefile system. These variables can be set in several
ways:
In the environment (e.g. setenv, export) -- not recommended.
On the make command line -- recommended.
On the configure command line
In the Makefile (only *after* the inclusion of $(LEVEL)/Makefile.common).
Should that *after* be *before*? *before* seems to be working for me.
