Hi Simon,

These are all already done in Makefile.maint :-)

That's why coreutils' Makefile.maint uses .x-sc* files
and an extra grep to filter each file list.

Mandate a specific target naming convention.  Then it's easy to process
all *.mk files in order to extract the matching target names.
Makefile.maint does this:

  # Collect the names of rules starting with `sc_'.
  syntax-check-rules := $(shell sed -n 's/^\(sc_[a-zA-Z0-9_-]*\):.*/\1/p' $(ME))

You can filter out such rules using a per-project setting of

local-checks-to-skip = ...

in Makefile.cfg.

If you want to use only a few rules, you should be able simply
(and concisely) to override the default definition of the checks to run.
I haven't tried it, but with Makefile.maint, setting
local-checks-available might be enough.
