I can't recall such a system. On x86_64, GNU ld would reject the resulting
text relocations anyway.

Agreed. On !allow_nonpic_in_shlib systems, the effect appears to be that we
quietly skip the plperl build, despite --with-perl, when the Perl build lacks
a shlib. This seems unhelpful; I think --with-perl should result in either an
error or a built plperl. Likewise for plpython. The coincidentally-better
build behavior under allow_nonpic_in_shlib should become unconditional.
