[PATCH v2] alpha: Use the generic gethostname

[Florian Weimer]

* Magnus Lindholm:

> alpha was the only target implementing gethostname with the syscall
> rather than through uname. Its only behavioural difference was the errno
> for a too-small buffer: it reported EOVERFLOW where the generic
> implementation, gethostname(2) and misc/tst-gethostname expect
> ENAMETOOLONG, so alpha failed that test:
>
>   tst-gethostname.c:96: numeric comparison failure
>      left: 112 (0x70, EOVERFLOW); from: errno
>     right: 63 (0x3f); from: ENAMETOOLONG
>
> The file contains nothing but that function, so removing it lets the
> sysdeps search fall through to sysdeps/posix/gethostname.c, which
> produces the same buffer contents and the expected errno.
> misc/tst-gethostname passes on alpha with it.

Looks okay to me.
