Subject: libnl-tiny: define _GNU_SOURCE if not defined
X-Git-Tag: v17.01.0-rc1~472
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3c1f20d0bb390f911c3da3334c6d94c19609c8c4;p=openwrt%2Fstaging%2Fxback.git

libnl-tiny: define _GNU_SOURCE if not defined

If _GNU_SOURCE was added as part of a package's TARGET_CFLAGS,
then compilation would fail for that module (especially if
warnings get treated as errors).
