Subject: [PATCH] native_bindir

Some libraries, like QT, have pre-processors that convert their input
files into something that the cross-compiler can process. We find the
path of those pre-processors via pkg-config-native instead of
pkg-config.

This path forces the use of pkg-config-native for host_bins arguments.

There are some discussions upstream to merge this patch, but I presonaly believe
that is is OE only. https://github.com/mesonbuild/meson/issues/1849#issuecomment-303730323

Upstream-Status: Inappropriate [OE specific]
