Unable to build ruby 3.1.0 on macOS when shared due to dylibs (libgmp) not found when running miniruby
Description
I am trying to develop a conan (the C/C++ package manager) recipe for Ruby. The recipe would allow downstream users to 1) get a runnable ruby executable, and 2) be able to link to ruby, or embbed it in a C/C++ program if built statically, in an easy way.
Currently there is an existing ruby 3.1.0 recipe that I'm trying to adapt, so I have to support this version.
First off, let me say that I can succesfully build with 3.3.0, so I know something has changed for the better since then. I'm just at a lost when figuring out what I need to backport to make 3.1.0 work.
The original issue is that it appears miniruby is looking for some dylibs and not finding them. Even if I do define LD_LIBRARY_PATH, DYLD_LIBRARY_PATH or DYLD_FALLBACK_LIBRARY_PATH (any combinations of these three) in my env.
dsymutil exe/ruby; { test -z '' || codesign -s '' -f exe/ruby; }
./miniruby \
-e 'prog, dest, inst = ARGV; dest += "/ruby"' \
-e 'exit unless prog==inst' \
-e 'unless prog=="ruby"' \
-e ' begin File.unlink(dest); rescue Errno::ENOENT; end' \
-e ' File.symlink(prog, dest)' \
-e 'end' \
ruby exe ruby

It seems that something is unsetting the variables, because this for eg works fine

My configure call is like this:

I have tried to backport https://github.com/ruby/ruby/pull/6296/files and https://github.com/ruby/ruby/commit/48644e71096c70132be9dfdcbfb414ec2e68d18b and https://github.com/ruby/ruby/pull/8730 amongst other things but I can't make it work. (I even tried a more brute force approach patching a lot of files by diffing 3.3.0 with 3.1.0, but please note I don't know what I'm doing... and I can get to the install step but then I get some errors about Psych / libymal and undefined Gem::Install:Zlib).
I would greatly appreciate if someone can spare some time to help me wrap this up (I've been trying to make the recipe work for so long that I'm about to give up...)
