[Buildroot] [git commit] p11-kit: fix argp_standalone build error

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=a7e8b6237458922f0a75103fb5c28e6fe713db7c
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

When BR2_PACKAGE_ARGP_STANDALONE is enabled and built before p11-kit the
configure script detects it and a conflict arises because libc already
includes and defines program_invocation_short_name.
Avoid this by forcing the detection to true otherwise the configure
script tries to use argp-standalone and it clashes with libc. Fixes:
