[Bug 41703] LdrUnloadDll is not suit for musl( musl lacks unload support though it has a dlclose())

https://bugs.winehq.org/show_bug.cgi?id=41703

--- Comment #8 from [e-mail] ---
Thx for your reply, Austin English.

I do find a way to check it explicitly and this should be worked for all libc.
But i need two programs to check it. I don't know how to write a correct
configure.ac.

As you can see, there're two programs in the attachment. Compile the second one
as a .so and run the first one. If glibc or other libc that support
unloading-after-dlclose(), we should see two lines of 'ss'. Or only one line if
the cureent libc is similar to musl.

Any help?
