BTW, as far as I can tell from the underlying discussion at
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=962138
there was no actual change in the existence of the shared
library, but what is now happening is that we are getting
a result reflecting the fact that /usr/bin/perl itself is
statically linked.
I wonder whether we could just drop the configure-time
test for useshrplib. The worst-case scenario is that a user
grinds through a build and eventually gets an obscure link error,
but that's probably quite uncommon these days.
