Release GNU make 3.81.

Update NEWS docs.
Enhance the manual to use automake version.texi, and use the canonical
FSF copyright features and statement.
Some $(realpath ...) tests won't work on Windows; leave them out
The jobserver filedescriptor test might fail if some FDs are reserved,
so for now comment out that check.
