TL;DR: on openbsd the various dl* functions are in libc. The attached
patch drops the -ldl here.
Longer version:
I wanted to try the native-comp. On OpenBSD gcc 10 isn't available, and
gcc 8 doesn't bundle libgccjit. I hacked the port of of gcc 8 to
provide also the libgccjit, but even if the "smoke test" worked,
building emacs with gcc8 and libgccjit failed. (this was a couple of
months ago at least). Today I gave it another shot and built gcc 10
from sources somewhere in my $HOME, and then managed to get emacs up and
running :) -- honestly, given the amount of hacks to get gcc10 working
in $HOME I am surprised nothing has exploded yet.
I still get a bunch of warnings (atm *Warnings* is 301 lines long), but
they are related to how I installed libgccjit and gcc10, not emacs
itself.
Anyway, none of the above is really about the patch. The only real
modification on the emacs side was to drop -ldl (and something related
get getopt_long, but I need to investigate that a bit more).
Thanks

I got it approved just a couple of days ago. Should I attach the pdf?
If it's enough, I submitted another patch recently[0] that was merged.
(sorry for the probably dumb question, but these are my first
contribution to a GNU project)
