"dlsym: resource temporarily unavailable" errors during build of lang/erlang on 11.3 i386

[Dave Cottlehuber]

On beefy[1] I see the same error repeatedly during i386-only builds. I googled
and am not even mildly enlightened [4]. Can anybody give me a hint please as to
what this is about?

gmake[5]: Entering directory '/wrkdirs/usr/ports/lang/erlang/work/otp-OTP-21.3.8.7/erts/emulator'
if utils/gen_git_version i386-portbld-freebsd11.3/gen_git_version.mk; then touch beam/erl_bif_info.c; fi
echo " PROFILE beam.prof.smp"

I've also read LLVM's profile data page [2] and maybe this is something we don't
even need to build at all?
