Subject: When cross-building, the CFLAGS and CXXFLAGS are for the target, and don't
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=1f22d6f131170f4dca02296fe266323d6339e6a3;p=oota-llvm.git

When cross-building, the CFLAGS and CXXFLAGS are for the target, and don't
apply to the build tools. If we want to allow build tool flags input, we
should have separate inputs (BUILD_CFLAGS and BUILD_CXXFLAGS, perhaps).
