Subject: [PATCH 1/1] Fix Makefiles for cross-compilation

The CFLAGS handling in mongrel2 is really messy and it is hard to make
it behave correctly with cross-compiling environments. This patch
restricts the Makefiles syntax to GNU Make, but help cross-compiling.

This is not meant to be applied upstream.
