Trying to pass an extra library to configure using LIBS, as configure
--help says I can, I found it did nothing, and traced it to
src/Makefile.in, which deliberately ignores LIBS. This dates back 14 years,
and whatever it was intended to fix no longer seems to be a problem. May I
install the following patch? With the patch applied, supplying LIBS on the
configure command-line worked exactly as it should.

Although I also dislike configure's mishandling of LIBS and would like 
to see it fixed, I don't think the proposed patch would work well, due 
to the funky treatment of LIBS in configure.ac.  Please look there for 
uses of SAVE_LIBS, pre_PKG_CONFIG_LIBS, PKG_CHECK_MODULES, LIBS_SYSTEM, 
LIB_PTHREAD, etc., and note that AC_CHECK_LIB etc. also futz with LIBS.
