This ticket upgrades lrslib to version 6.2. This version, according to
http://cgm.cs.mcgill.ca/~avis/C/lrs.html, has the following new features:
- (new in 6.0) mplrs: C wrapper for lrs that allows for parallelization
on clusters of machines and uses the MPI library quickstart
- (major revision in 6.1) lrsnash, 2nash: Computes all Nash equlibria of
a two person non-cooperative game. 2nash is a 2-processor parallel
version
Since Polymake (#20892) seems to need the shared library of lrslib, but
lrslib uses a hand-written makefile that does not work on Mac OS X, I have
added an autotools build system. It is available here:
https://github.com/mkoeppe/lrslib/tree/autoconfiscation
"Upstream" URL:
https://github.com/mkoeppe/lrslib/releases/download/lrslib-062%2Bautotools-2016-07-05/lrslib-062.autotools-2016-07-05.tar.gz
Download and put into upstream under the name
"lrslib-062+autotools-2016-07-05.tar.gz"

Comment:
This looks good to me now; thanks.
Note to Volker, you will have to rename the tarball when you put it on the
server.
