   4 Subject: [PATCH] configure: do not check for libbsd
   5
   6 libbsd causes build issues because its libbsd-overlay.pc file is borked:
   7 it contains -isystem in CFLAGS, which is not munged by pkgconf, so we
   8 end up using the headers of the build machine, causing all sorts of
   9 hard-to-debug trouble at build time.
  10
  11 lldpd uses libbsd-overlay for a few helper functions, but has fallbacks
  12 in case it is not available. The only feature that is lost when not using
  13 it is that the neighbour name is no longer displayed in /proc/self/cmdline.
  14 As the author of lldpd said on IRC: "people should survive! ;-)"
  15
  16 So we just remove the detection of libbsd altogether.
