# configure WITHOUT pkg-config" instructions.
#
# Unfortunately, some site Linux systems are quite old and have a
# version of pkg-config that avahi refuses to work with.
# Consequently, we place $(HostBinDir) first in the path to ensure
# that the project-local version of pkg-config is detected and used
# rather than a host- or site-local version.
