From 730fe2ee2fb9e08cbe885f370afe83fecb18d048 Mon Sep 17 00:00:00 2001

Subject: [PATCH] btrfs-progs: Pass CFLAGS and LDFLAGS to Python
Adds Make variables EXTRA_PYTHON_CFLAGS and EXTRA_PYTHON_LDFLAGS which
can be used to pass CFLAGS and LDFLAGS respectively when building the
Python library.
This is required to support reproducible builds, as there are often
compiler and linker flags that must be passed in order to generate
reproducible output (e.g. -fdebug-prefix-map)

Upstream-Status: Accepted [https://github.com/kdave/btrfs-progs/pull/176]
