Subject: allow 'make CPPFLAGS=<something>' work again
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=4ecaedc771f47e099609c69ed2782c64fc653d05;p=oota-llvm.git

allow 'make CPPFLAGS=<something>' work again

this makes this hack a bit more bearable
for poor souls who need to pass custom
preprocessor flags to the build process
