[ thinks ... ] OK, so the problem case is where perl was built with a
different compiler than we're building PG with, and hence ccdlflags
may contain incompatible switches. That's a fair point, though it seems
like a shaky assumption that the rest of ldopts isn't also compiler-
specific.

Where would he get it from, then? We did talk about providing macros
for more flexible specification of rpath, so we can fix the problem if
we can get the Perl library path, but I'm unsure where to learn that.
