"$(STAGING_DIR)/include" was carried over from buildroot-ng to OpenWrt
in commit 60c1f0f64d23003a19a07d6b9638542130f6641d. buildroot has
dropped this directory a long time ago.

In OpenWrt the directory is still created by the PrepareStaging macro
and is part of the default TARGET_CPPFLAGS. But nothing at all installs
headers into this directory, nor should anything be installed under this

Removing this directory from TARGET_CPPFLAGS will cut down the log noise
a bit. Not only will CPPFLAGS be shorter, there will be less warnings
set off by "-Wmissing-include-dirs" (or even failures when paired with
"-Werror"). After all the directory does not even _exist_ in the SDKs,
which are used on the build bots when building packages (see [1] and
