From 7ee197885e113878aedab58bdda80302e42aff4c Mon Sep 17 00:00:00 2001

Subject: [PATCH] build system fixes

This touches up the homebrewed build system to work much better "out of the
box" for people.  Specifically:
	- allow toolchain vars to be set via environment
		- CC / BUILD_CC / AR / RANLIB
		- CFLAGS / CPPFLAGS / LDFLAGS
	- split CPPFLAGS out of CFLAGS
	- break -fPIC out of global CFLAGS and only use where needed
	- use LDLIBS for libraries, not LDFLAGS
