Finally got through a fresh build - on the system with detuned glibc
I'd expected the tests to pass, but still both check and bash had
sigfpe errors.  I then tried running the check tests on my desktop
(the host system with detuned glibc) and was surprised to find they
too failed.

Booted the new system, the tests passed.  Gradually building the new
system, running the check tests from time to time, all good.
Completed enough to use startx - in the tty the tests passed, but in
my term they again failed.

Turns out I'v been looking in the wrong place: I use rxvt-unicode.
Once I started to suspect that might be the problem, google found
http://lists.schmorp.de/pipermail/rxvt-unicode/2013q3/001839.html
and at the beginning of that thread is a link to the perl issue:
https://github.com/Perl/perl5/issues/12349

In (embedded) perl, sigfpe doesn't get passed through.

Thanks again for your assistance,
