[Buildroot] [git commit] boot/uboot: fix uboot building host tools on x86 architecture

[Yann E. MORIN]

commit: https://git.buildroot.net/buildroot/commit/?id=2eaa6d0f36291f49ab56a734a4851a6ffe8e8803
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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 add pkg-config environment variable to configure it for host.

Add a test to avoid future regress on the build of U-boot.
