Allow BUILD_CFLAGS and TARGET_CFLAGS to be specified at configure time
Currently, we're unconditionally setting the build and target cflags in
the configure script, which means that they can't be easily
overwritten.
This change conditionally sets these variables if they're not specified
during configure, allowing something like:
BUILD_CFLAGS=-Werror ./configure
