(a) This enables the malloc wrap also on Hurd, as used on Linux already; Perl's own test suite passed with it, and I see no reason to diverge from the behaviour on Linux and kFreeBSD. I'm not sure whether it affects the ABI though, so it might be safe only for the upcoming perl 5.24 in experimental (since that breaks the ABI anyway) (b) This improves the reporting of the GNU libc used, so it's shown in `perl -V` (as libc value, instead of the currently empty string).
