Hello, you have provided good fix but it is related to armv7 only.
For example: aarch64-gentoo-linux-musl and aarch64_be-gentoo-linux-musl are valid CHOSTS, but first one works fine, second one fails.
First one is using "rb_cv_coroutine=arm64", second one is using default "rb_cv_coroutine=ucontext".
Same thing will be true for s390x, other arches: it will try to use default broken (for musl) "rb_cv_coroutine=ucontext".

@luizluca have provided right fix - it works perfect. https://github.com/ruby/ruby/pull/3567

Hello,

While building ruby 2.7.0 for mips with musl, it fails:


```

```

It seems that now ruby either uses native ASM code or ucontext for coroutine.
Both are unavailable in my crossbuild. It was building and running with 2.6.x:

```
configure:25935: checking native coroutine implementation for mips-linux-gnu                       configure:25976: result: no
```

With 2.7.0:

```
configure:26536: checking native coroutine implementation for mips-linux-gnu                       configure:26601: result: ucontext
```

I tried to disable it with --without-coroutine, --with-out-coroutine and --with-coroutine=no, but it is innocuous or try to use a "no" implementation.

It looks like this introduced the change https://github.com/ruby/ruby/commit/7291fef55c90b9ab6b3c22018b16972861b98c9d

And musl might never fix it:
