buildroot/package/pkg-utils.mk
Yann E. MORIN 242e0087e5 core: move pkg-utils.mk to support/
pkg-utils.mk contains various definitions that are used in the package
infrastructures and packages themselves.

However, those definitions can be useful in other parts of Buildroot,
and are already used in a few places that are not related to the package
infrastructure. Also, $(sep) will be needed early in the Makefile when
we eventually support multiple br2-external trees.

Since this file only contains definitions, we can include it anytime.

So, consider that file to no longer be specific to the package infras:
  - move it to support and rename it,
  - move a few similar definitions from the main Makefile to that file.
