bug#70411: [bug] install(1) fails to read /dev/stdin on Darwin

[Alejandro Colomar]

Hi!

I don't own a Darwin system, so I can't help much reproduce.  However,
I've received a bug report to the Linux man-pages, that our build
system (GNUmakefile-based), which ends up calling

        ... | install /dev/stdin $@

doesn't work on Darwin.  Here's the original bug report:
<https://github.com/NixOS/nixpkgs/pull/300797>.

Here are the reported error messages:

...
INSTALL         
/nix/store/3s28l9ijlkmsq8256zdxjvl173gkn37c-man-pages-6.7/share/man/man3/addseverity.3

I don't see why install(1) should fail to read /dev/stdin under any
POSIX system.
