Subject: [PATCH] Revert "Do not override environment CFLAGS and CXXFLAGS"

This reverts commit 80ebd60e7ca3c48a19b94ddaeebb23182b703178. The
reason why we cleared CFLAGS/CXXFLAGS was because otherwise we get a
default value of -O2, which interferes with the defaults set in the
Makefile. (E.g. "make OPTIMIZE=0" should not pass -O2.)
