rm: handle -f w/no arguments gracefully
Fixes automake bug https://bugs.gnu.org/10828.
Delete the configure check that would abort if `rm -f` does not work,
and delete the plans to make this a hard requirement in the future.
Instead, test to see if `rm -f` fails w/out arguments. If it does,
define am__rm_f such that it always passes at least the "" argument
when deleting files. If it doesn't fail, then we can omit the "".
Then go through lib/am/ and update places where we use the pattern
`test -z ... || rm -f ...` and replace with $(am__rm_f).
* NEWS: Mention support for `rm -f` w/out arguments.
* PLANS/rm-f-without-args.txt: Remove.
* lib/am/check.am: Use new $(am__rm_f) helper.
* lib/am/clean.am: Likewise.
* lib/am/header-vars.am: Likewise.
* lib/am/inst-vars.am: Likewise.
* lib/am/libs.am: Likewise.
* lib/am/ltlib.am: Likewise.
* lib/am/progs.am: Likewise.
* lib/am/texinfos.am: Likewise.
* m4/init.m4: Delete `rm -f` checks and call _AM_PROG_RM_F.
* m4/rmf.m4: Define new _AM_PROG_RM_F macro.
* t/rm-f-probe.sh: Update test.
