I built cmake (and all the things it depends on) from scratch using
12.1-PRELEASE @ r352356 on a Wandboard (armv7); no problems.

You mentioned using an Rpi-B... maybe the problem is specific to armv6.
I have an old rpi-b somewhere, but given how long it took a wandboard
to build cmake yesterday (many hours), I can only imagine it would take
days to get to the failure point on an rpi-b.  (I.e., I'm not even
going to try.)
