[Buildroot] [PATCH 1/1] package/libcap: fix regression for static linking issue

[Heiko Thiery]

9c13e02c35c74eca56e69f2bbfde452b51860f5e already fixed the static linking
issue for host-libcap on some distros (e.g. on Fedora32 and openSUSE).

This regression was introduced by 8d38eb052e7006b6e74e9453351d7f245144481e.

An upstream patch [1] is added to address this problem [2].

Fixes:
Bug 13296

I've got feedback from Ian about testing the patch. Unfortunately he
is not registered to the mailing list to send the tested-by by
himself. So I will do that in his name.



Thank you
