[Buildroot] [PATCH 1/2] efivar: new package

[Thomas Petazzoni <thomas.petazzoni@free-electrons.com>]

Hello,

This patch looks mostly good. There are only a few nits, see below.

We try to avoid first person sentences in commit log. Can you rephrase
as: "so a patch was prepared for it, and was submitted upstream".

Does it build on all architectures, or is it somehow x86/x86-64
specific ?

GPLv2.1 doesn't exist. It's either GPLv2 or LGPLv2.1. Looking at the
code, it seems to be LGPLv2.1.

Please use CFLAGS="$(HOST_CFLAGS) -std=c99" instead of CFLAGS+=

This should be done in a post-patch hook, or maybe even by a patch
itself? Or maybe you don't need any patch at all, by just passing
BINTARGETS=efivar when building/installing ?

Since you also need libdir at each step, shall I suggest that you do
something like:

EFIVAR_MAKE_OPTS = \
	BINTARGETS=efivar \
	libdir=/usr/lib

and then use $(EFIVAR_MAKE_OPTS) at build and install time ?

Could you address those issues and send an updated version?

Thanks!
