[PATCH 1/6] bootstrap: set and use PATH_SEPARATOR

[KO Myung-Hun]

A PATH separator may be different in according to systems. For
examples, OS/2 uses ';'.

* bootstrap (Shell normalisation): Set PATH_SEPARATOR properly.
(func_check_tool): Use PATH_SEPARATOR.
* build-aux/gl/build-aux/bootstrap.in (func_check_tool):
Use PATH_SEPARATOR.
* build-aux/gl/build-aux/funclib.sh (Shell normalisation): Set
PATH_SEPARATOR properly.
