Support musl platforms: LoadError on aarch64-linux-musl

[beqdot]

I'm using docker with Ruby alpine 3.1 image (on Mac M2 if that matters) and got this error:

/usr/local/bundle/gems/activesupport-6.1.7/lib/active_support/dependencies.rb:332:in `require': cannot load such file -- sqlite3/sqlite3_native (LoadError)
...
Error relocating /usr/local/bundle/gems/sqlite3-1.5.4-aarch64-linux/lib/sqlite3/3.1/sqlite3_native.so: fcntl64: symbol not found - /usr/local/bundle/gems/sqlite3-1.5.4-aarch64-linux/lib/sqlite3/3.1/sqlite3_native.so (LoadError)

The same situation happened with the gem 'nokogiri', but this is solved by adding gcompat lib (solution from docs https://nokogiri.org/tutorials/installing_nokogiri.html#linux-musl-error-loading-shared-library).

Now I make it with gem install sqlite3 --platform=ruby but native build could be much better for build time

@beqdot Thanks for opening this issue. We do test the precompiled native gems on x86_64 musl, and it works fine there. I'll need to investigate why aarch64 is behaving differently.

Here's how I reproduced:

Please follow #442 for the fix-in-progress for this issue.

[flavorjones]

Should be fixed in v2.0.0 with the linux-musl native gem.
