[LTP] [PATCH v3 2/2] include/Makefile: Fix cleaning targets

[Petr Vorel]

Hi Ricardo,

[ Cc Joerg, who touched build system in the past. ]

> Add ac-clean target as dependency of ac-maintainer-clean and add missing

> targets can make use of it. Also, add "compile" to the AUTOMAKE_FILES
> list.

nit: You also remove stamp-h1 from AUTOMAKE_FILES. Why? Did I suggest that?
It's created by configure (e.g. not automake), but I considered AUTOMAKE_FILES
holding files created by autotools.

FYI: we usually don't keep Cc: in the commit message (git format-patch --cc ...
or git send-email --cc ... has the same effect - sending mail, but don't
preserve it). Of course it can stay. I personally see more value with adding
Link: tag to patch in lore (for these who want/need to dig in history).

nit: Wouldn't be better to have another variable which would be used in for loops?
