I'm just guessing, but your build error looks like you are also
cross-building the tools, which is wrong. You want them to be host-tools.
So don't export PKG_CONFIG_SYSROOT_DIR, it would then try to link target
libraries into a host binary.

I have looked again how I do it:

# this is for additional _host_ .pc files
export PKG_CONFIG_PATH=${prefix}/lib/pkgconfig

Then have a target-pkg-config, so this code inside several kernel Makefiles
will work:

PKG_CONFIG ?= $(CROSS_COMPILE)pkg-config

And then export your PKG_CONFIG_SYSROOT_DIR and the like inside that. I bet
you have all of this already in place, so just remove the SYSROOT_DIR from
your kernel build script and things should work.

Thank you for your comments! I will try this in our environment in the
upcoming days.

Greetings!
