UNIXROOT on OS/2 is used to specify a drive where unix FHS is
installed. If M4 is not executed on a drive where it exists without
UNIXROOT support, modules cannot be located. Because '/' is a root of
a current drive.
* m4/path.c (UNIXROOT): Define it on OS/2 or empty string on others.
(m4__include_init): Prepend UNIXROOT to PKGLIBDIR.
