man/*.1 files, and that command would run concurrently with the one
that installs "/P/bin/install" itself. We would run this command:
"src/ginstall src/ginstall /P/bin/install", and it would result
in intervals during which the destination file does not exist,
is empty or incomplete and not executable. We addressed this
problem long ago for installation of actual binaries by telling the
installation rules to use our just-built bin/ginstall (only when not
cross-compiling) rather than the PATH-resolved "install" program.
This change is to do the same for those .1 files.
* src/local.mk (INSTALL): Override automake's default of something
like "INSTALL = /P/bin/install -c".
(INSTALL_PROGRAM): Now that we set INSTALL, there is no longer any
need to set this derived variable. Its default definition,
"INSTALL_PROGRAM = ${INSTALL}" does what we require.

tests: fix false failure with FreeBSD 11 multibyte quoting
* tests/misc/printf-quote.sh: FreeBSD 11 was seen to treat
\u0378 as a printable character. Therefore change to
using the \u0081 C1 control character. We use the UTF-8
representation because our printf implementation explicitly
disallows \u0081 as input.

This provides better alignment when some names are quoted,
