I think the same needs to be done for AC_PATH_TOOL. Maybe some day in the
future it will be possible to factorize the code for both macros, but
until then we should keep them in-sync.

You probably don't need to describe bad things in the ChangeLog as long as
they can be trivially deduced :-)

        * acgeneral.m4 (AC_CHECK_TOOL): Set $1 also when using the cache.
        (AC_PATH_TOOL): Likewise.
