MORIN" <yann.morin.1998@free.fr>Date: Sun, 14 Aug 2016 12:15:17 +0200Subject: [PATCH] configure: do not check for libbsdlibbsd causes build issues because its libbsd-overlay.pc file is borked:it contains -isystem in CFLAGS, which is not munged by pkgconf, so weend up using the headers of the build machine, causing all sorts ofhard-to-debug trouble at build time.lldpd uses libbsd-overlay for a few helper functions, but has fallbacksin case it is not available. The only feature that is lost when not usingit is that the neighbour name is no longer displayed in /proc/self/cmdline.As the author of lldpd said on IRC: "people should survive! ;-)"So we just remove the detection of libbsd altogether.Fixes: http://autobuild.buildroot.org/results/6b7/6b70fa379e834ec71cc260ba6af771b531ca3511/ http://autobuild.buildroot.org/results/769/769074c4bb67336ae6679f2c1cd2a8220d2bec24/ http://autobuild.buildroot.org/results/c8a/c8a6001f437701ecc75f6c9252935645bda8a8c8/ [...]Signed-off-by: "Yann E.
