Subject: [PATCH 4/4] linux-user/syscall.c: remove wrong forward decl of setgroups()

this declaration is wrong:
the correct prototype on linux is:
int setgroups(size_t size, const gid_t *list);

since by default musl libc exposes this symbol in unistd.h additionally to grp.h, the wrong declaration causes a build error.

the proper fix is to simply include the correct header.

In your patch, you replaced a wrong forward declarationof function setgroups by an include statement using grp.h. That's fine.

There are more extern declarations in linux-user/syscall.c. Even if they are correct, they should be replaced by include statements. If there will be a v2 of your patch series, you could add patches for those declarations, too.
