utmp function family missing on musl

[Ecordonnier]

Hello,
functions like getutxent, setutxent, endutxent, struct utmpx, etc. are missing from the musl implementation ( src/unix/linux_like/linux/musl/mod.rs ), even though those functions are implemented in musl (see https://git.musl-libc.org/cgit/musl/tree/include/utmpx.h ).

As reference, see this commit which added the function for solaris, as well as the man page: https://linux.die.net/man/3/endutxent

Why is this trying to change O_LARGEFILE?

[Ecordonnier]

@joshtriplett did you mean to ask this in the pull-request?

[joshtriplett]

@Ecordonnier Yes, thank you.

Is this waiting on version 0.3 (#3213 (comment))?

[Ecordonnier]

Yes it is waiting on 0.3 (which was renamed to 1.0, see #3248 )
