[PATCH] {master} acinstall: remove, it has never been really used

[Stefano Lattarini]

Accordingly to the git history (see for example the 'README-alpha'
in commit 'Release-1-1e-39-g9beb4ec' of 06-10-1996), the 'acinstall'
script should have been used to install m4 files for aclocal.  The
comments in this script report that "... A script is needed to do
this because we want to do serial-number checking; newer versions
of macro files should always be preferred".

But the 'acinstall' script has never been really used: for example,
the entry "actually use acinstall program" was removed (unfixed)
from the TODO file in commit 'Release-1-1k-12-g1201405' of
08-12-1996, and the only citation of 'acinstall' in the manual was
removed in commit 'Release-1-1l-37-g128c3d7' of 19-03-1997, and
never added back. In addition, the last non-trivial edit to the
script (that is, besides updates to the copyright notice) dates
back to 1996.

More importantly, now that aclocal supports the ACLOCAL_PATH
environment variable, installing m4 files directly in the
system-wide acdir is discouraged, and better left only to
distros' package managers (which already have their own way to
do so, with which third-party build systems should not directly
meddle).

So we just remove the 'acinstall' script.

* lib/acinstall: Remove.
* lib/Makefile.am (dist_script_DATA): Update.
