Committing the perl 5.24 that Dr Bainbridge successfully built on Ubuntu 16.06 against (a locally compiled, non-system) perl 5.24 perl. It is a byproduct of compiling up a gs3-svn on the Ubuntu 16.04 with the perl 5.24 in the PATH. This perl-5.24 folder was copied from the gs3-svn's gs2build/perllib/cpan folder. It's being committed into the release-kits area as other versions before have been, as it's needed for release-kits, to generate binaries that will work with perl 5.24. However, the version we generated only has Expat.so, not le Expat.bs. Not sure if that's still necessary, and if so, how it should be generated. See http://www.cryst.bbk.ac.uk/CCSG/programming/perl/PerlDoc/lib/ExtUtils/Mkbootstrap.html for ideas, if the bs extension stands for bootstrap as it seems to.
