libxcb-devel: install static libraries
https://github.com/void-linux/void-packages/pull/31959

Description:
So you can statically link against X programs; since libX11 links
against libxcb this is impossible now.

Either I'm not understanding how static linking works (AFAIK you *need*
the .a file?), or this is a very unpopular thing to do as it's been like
this for 9 years (changed in commit 9526648, in 2012) 🤔
