originally, the gettid wrapper was needed on glibc and musl,
glibc-2.30 added a gettid function, so now it is only needed on musl

Subject: [PATCH] Fix a future-compat warning
```
warning[E0506]: cannot assign to `self.input.cached_token` because it is borrowed
--> src/parser.rs:591:17
|
566 | pub fn next_including_whitespace_and_comments(&mut self) -> Result<&Token<'i>, BasicParseError<'i>> {
| - let's call the lifetime of this reference `'1`
...
579 | Some(ref cached_token)
| ---------------- borrow of `self.input.cached_token` occurs here
...
591 | self.input.cached_token = Some(CachedToken {
| ^^^^^^^^^^^^^^^^^^^^^^^ assignment to borrowed `self.input.cached_token` occurs here
...
603 | Ok(token)
| --------- returning this value requires that `self.input.cached_token.0` is borrowed for `'1`
|
= warning: this error has been downgraded to a warning for backwards compatibility with previous releases
= warning: this represents potential undefined behavior in your code and this warning will become a hard error in the future
```
