[PATCH] Fix conform linknamespace tests due to gnu_dev_makedev

[Florian Weimer]

* Stefan Liebler via Libc-alpha:

> If building on s390 / i686 with -Os, various conformance
> tests are failing with e.g.
> conform/ISO/assert.h/linknamespace.out:
> [initial] __assert_fail -> [libc.a(assert.o)] __dcgettext -> [libc.a(dcgettext.o)] __dcigettext -> [libc.a(dcigettext.o)] __getcwd -> [libc.a(getcwd.o)] __fstatat64 -> [libc.a(fstatat64.o)] gnu_dev_makedev

> The usage of gnu_dev_makedev was recently introduced by
> usage of the makedev makro in commit:

> linux: Use statx for MIPSn64

> This patch is now linking against __gnu_dev_makedev as
