[Buildroot] [PATCHv7 1/5] pkgconf: new package

[Gustavo Zacarias]

pkgconf is a drop-in replacement for pkg-config that doesn't need
itself to build and just requires a C89 compiler.

Instead of using a patch for hardcoded sysroot support (as the patch to
pkg-config does) we rely instead on a wrapper script that takes the
appropiate action.

+[PATCH] prefix sysroot to include/libdir path variables
+
+Prefix includedir / libdir variable values with sysroot if a variable is
+requested (--variable=<name>), similar to how it's done for -I / -L flags.
+
+This is sometimes used to find header files (E.G. in gst-plugins configure),
+so ensure the sysroot'ed files are used.

This line doesn't really belong here (it should go in the commit
removing host-pkg-config), but as it's the same value the pkg-config.mk
one, it's not a big deal.

Committed entire series, thanks!
