make: support $+ and $^ as POSIX 202X features
Austin Group defect reports 514 and 1520 have both been accepted.
Together these introduce the internal macros $+ and $^:
- $+ lists all prerequisites, with duplicates retained;
- $^ lists all prerequisites, with duplicates removed.
$^ had already been implemented as a non-POSIX extension, it now
becomes a POSIX 202X extension. $+ has been added as a POSIX
202X extension.
Neither of the above defect reports mentions how $? should handle
duplicate prerequisites. In POSIX mode duplicates are retained.
Removal of duplicates is implemented as a non-POSIX extension to
match existing practice in other versions of make.
