[PATCH] S390: Get rid of linknamespace failures for utmp functions.

[Stefan Liebler <stli at linux dot vnet dot ibm dot com>]

Hi,

i get the following linknamespace-testsuite failures on s390-32:

The commit 4057dc459ae9de59c67628db3db844c7a3765d00
introduced symbol-versioning for those utmp functions with
the macro default_symbol_version, which expands to strong_alias
in the STATIC-case.
But in common-code those funtions are weak aliased.

Thus this patch uses default_symbol_version in the SHARED-case
and weak_alias in the STATIC-case.

The mentioned testsuite-failues are passing now
and there are no new failures.

Ok to commit?

Bye
Stefan
