From 17e5e3e7f647343dafa701b95628b5160790e2a4 Mon Sep 17 00:00:00 2001
From: Mike Frysinger <vapier@gentoo.org>
Date: Wed, 10 Feb 2016 09:47:27 +0100
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
Signed-off-by: Mike Frysinger <vapier@gentoo.org>
Forward ported from libcap-2.24 to libcap-2.25
Forward ported from libcap-2.25 to libcap-2.28
Forward ported from libcap-2.28 to libcap-2.29
Forward ported from libcap-2.29 to libcap-2.33
