[PATCH] btrfs-progs: allow CFLAGS specification in new build

[Eric Sandeen <sandeen@redhat.com>]

Disclaimer: I am not an auto$FOO expert by any means.

But I could find no way to specify additional CFLAGS, and I think
that this is because they are hard-coded in configure.ac.

The below works for me, but I don't know if it's the right solution...
