illumos gate

<alanc> btw, if you need a bite-size bug for a newbie, https://github.com/illumos/illumos-gate/blob/master/usr/src/lib/libc/port/gen/confstr.c#L75 should probably say -m64, since that's what gcc, clang & modern Studio use (modern Studio bitches that -xarch=generic64 is obsolete) - test case is  /usr/bin/getconf -a
<richlowe> should probably fix it all to speak gcc
<richlowe> (no -Xa, either)
<richlowe> technically incompatible, but surely getconf talking about compilers people actually use would be for the best.
