make: comments in macro expansions and command lines
The POSIX specification says:
There are three kinds of comments: blank lines, empty lines, and
a <number-sign> ('#') and all following characters up to the first
unescaped <newline> character.
Most implementations don't treat '#' in a macro expansion or a command
line as the start of a comment. POSIX doesn't mention either of these
exceptions.
Permit the exceptions as a non-POSIX extension.
