add new AC_PROG_AR helper
This mirrors the existing RANLIB and related toolchain macros that
autoconf already exports. Some projects assume `ar` is available
which isn't always safe, so provide a macro that probes the full
toolchain settings.
This also makes it easier to use AC_REQUIRE with the macro instead
of duplicating the AC_CHECK_TOOL call in projects.
* lib/autoconf/programs.m4 (AC_PROG_AR): New macro.
* doc/autoconf.texi: Document it.
* tests/local.at (_AT_CHECK_ENV): Allow $AR output variable.
