Hello Kory,

The make all command run the tools/makefile on the process.
This makefile use "pkg-config" command to support static link.
The issue is the use of pkg-config configured for crosscompiling
to build binaries tools for host architecture.
To fix it, I copied the behavior of QtWebengine by using a pkg-config
executable preconfigured for host.

Thanks for the patch. It would require a better commit title though, as
"fix uboot build" is very vague.

After discussing with Yann E. Morin on IRC, could you try this change
instead:

	$(TARGET_CONFIGURE_OPTS) \
	        PKG_CONFIG="$(PKG_CONFIG_HOST_BINARY)" \
        	PKG_CONFIG_SYSROOT_DIR="/" \
	        PKG_CONFIG_ALLOW_SYSTEM_CFLAGS=1 \
	        PKG_CONFIG_ALLOW_SYSTEM_LIBS=1 \
	        PKG_CONFIG_LIBDIR="$(HOST_DIR)/lib/pkgconfig:$(HOST_DIR)/share/pkgconfig"

The reasoning is that U-Boot anyway only uses pkg-config for host
tools, so we could just as well pass those environment variables when
building U-Boot.

Could you try this out?

Also, do you have a Buildroot .config to reproduce the issue? Perhaps
it would be nice to have a test case in our runtime test infrastructure.

Thanks!

Thomas
