From: Chun-Tse Shao <ctshao@xxxxxxxxxx>
commit d5ea4fece4508bf8e72b659cd22fa4840d8d61e5 upstream.
Add HOSTPKG_CONFIG to allow tooling that builds the kernel to override
what pkg-config and parameters are used.

[swboyd@xxxxxxxxxxxx: Drop certs/Makefile hunk that doesn't
apply because pkg-config isn't used there, add dtc/Makefile hunk to
fix dtb builds]
