Description
Hi.
Homebrew/Linuxbrew maintainer here. We struggle to build QT since release 5.12.1 at least, on various versions of Ubuntu (16 and 18). We ship our own dependencies so packages/files will not be in common linux include/lib folders. The build was working fine before.
The build fails with:

See https://github.com/Homebrew/linuxbrew-core/pull/11696
We have:
$ pkg-config --libs xcb -L/home/linuxbrew/.linuxbrew/Cellar/libxcb/1.13.1/lib -lxcb
It looks like the -lxcb flag is not correctly passed. In release 5.12.1 I was able to hack around this by patching some files and add `-lxcb`, which fixed the issue. For release 5.12.2 I have no clue how to properly fix this.
