Comment(by altaic):

 Oops! I somehow mixed things up when I mentioned libraries/integer_gmp and
 libraries/unix (I had a different failure with them, which was due to them
 being automatically configured for i386 even though I'd specified x86_64
 to the overall configure script).

 I typed up a huge response detailing two bugs (plus workarounds and
 resolutions) with the build system that caused build failure at unlit, but
 I've instead decided to split them into separate tickets. Since they block
 this ticket, I'll post a comment here after filing them (and others I
 find) tonight.
