If you do that, you have to fix a lot of other places, too. This starts in
scripts/kconfig/ and also includes e.g. tools/testing/.

Usually you have pkg-config for host and ${target_platform}-pkg-config for the
target, and the PKG_CONFIG variable for the target, usually initialized to $
(CROSS_COMPILE)pkg-config. I have sent a bunch of patches to replace the usage
of plain pkg-config at several places with the cross-aware version, but sadly
a lot of them have not been picked up. It break cross-building tests basically
all the time. One example is here:

For me it looks like you are trying to go into the wrong direction.
