Sorry for replying to my own email, but after compiling, the test suite
crashed on the xeigtstz_* with Segmentation Fault errors.

I debugged this a little bit and the reason was these tests use a lot of
local (i.e. stack) variables -- so many in fact that they trigger a
stack overflow on entry.

Disabling stack size limit (mine was 8192 KB) with
  ulimit -s unlimited
before calling dpkg-buildpackage fixed things for me.

I hope this avoids someone the half hour I spent in gdb searching for a
bug that probably isn't there.
