FYI: install-sh uses FYI=/

[Alexandre Duret-Lutz]

I'm installing this on HEAD.
This patch suppresses the '%' and '@%:@' failures in Paul's test.

The "Some sh's can't handle IFS=/ for some reason." comment is
there since install-sh has been added to Automake in 1995, so I
don't know where it comes from.  (It's not in the original X11R5
version.)  I believe this is a myth, and that the author was
probably confused by the fact that some shell might create an
empty word when splitting a string that start with $IFS.

        * lib/install-sh: Use IFS=/ to split directories on /, don't translate
        / into % as it prevents directory names using %...
