### Build libpipeline #####################
# libpipeline is a pretty niche-market library. It used to be bundled
# in the man-db source, and as far as I can tell, nothing else uses it.
# Instead of making it a separate build and external dep, we'll just
# bundle it here.

# Apply Patches:
#
# The 'checking for long filenames' test in the configure script writes to
# /usr/lib, which is bad behaviour for a configure script. Not to mention
# wrong (it assumes configure is always being run as root). We already
# know we have long filename support, because we live in the 21st century
# now, so this patch gets rid of the test and force-enables it.

# gets broken by libtool (it *insists* on replacing -lpipeline with
# /usr/lib64/libpipeline.so, which will fail if it's an older version).
