[committed] Require hello-gnu-pubnames for pr24771.sh

[Tom de Vries <tdevries@suse.de>]

Hi,

On the dwz-centos-* buildbots (apparantly with an older gcc) we see:
...
cc hello.c -o hello-gnu-pubnames -g -ggnu-pubnames
cc1: error: unrecognised debug output level "gnu-pubnames"
make: *** [hello-gnu-pubnames] Error 1
...

Fix this by allowing the hello-gnu-pubnames to fail, and requiring
hello-gnu-pubnames for pr24771.sh.

Committed to trunk.

Thanks,
- Tom
