Further testing indicates that it indeed works to install in a
non-ASCII directory after building.  But it only barely works, at
least in my testing: the various files and directories in
doc-directory, load-path, etc. are unibyte strings, so using them only
works if they are passed to file primitives.  If you try to invoke a
program with one of these values as a command-line argument, the
program will fail (unless your locale encoding is identical to
file-name encoding).  And even using the unibyte strings in
conjunction with files is fragile, as, for example, 'equal' will not
compare unibyte and multibyte strings of the same bytes as equal.
