gnupg2-1.9.91 build failure (fedora core/x86_64)

[Rex Dieter]

gnupg2 on x86_64 segfaulting in tests again/still.  I had been mostly
ignoring those (hoping that they'd just go away someday), but now the tests
seem to run during the regular build not just 'make check'.

Tail end of the build.log is appended.

Any further debugging that I can do (now that I actually have an x86_64 box
to test with)?
