[PATCH] Makefile: remove the 'hdr-check' target

[PATCH] Makefile: remove the 'hdr-check' target

[Ramsay Jones]

The 'hdr-check' target has proved to be costly for some developers and
platforms, depending on the configuration, even when not using this
target. In part, this is due to the use of $(FIND) in the definition
of the $(LIB_H) variable. This effectively reverts commit ebb7baf02f
("Makefile: add a hdr-check target", 2018-09-19).

As I said elsewhere, I think it would make sense to keep this target, and
to wire it up to our CI builds.

Ciao,
