Linker failure on macOS in shared library

[sternenseemann]

Building the lowdown shared object on macOS will currently fail like this:

clang -shared -o liblowdown.so.1 autolink.o buffer.o diff.o document.o entity.o gemini.o html.o html_escape.o latex.o library.o libdiff.o nroff.o odt.o smartypants.o term.o tree.o util.o compats.o   -Wl,-soname,liblowdown.so.1
ld: unknown option: -soname
clang-11: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [Makefile:168: liblowdown.so] Error 1

This is not surprising, as the lack of a .dylib target already indicates this is not explicitly supported. The question is, do you want to support it upstream? Would you accept patches?

Sure, don't hesitate to patch anything you'd like!

This has been fixed in recent commits and will appear in the next version. Thank you!

Can oconfigure determine the file extension for shared objects somehow? A remaining problem on darwin seems to be that it is still installed as .so and not .dylib. (I also believe the way versioned shared objects are named is different on darwin, but I'd need to look it up.)
