[patch] 2.58: Absolute paths no longer such

[Maciej W. Rozycki]

Hello,

 As of autoconf 2.58, the abs_* variables documented as set to respective
absolute paths are no longer set thus -- they contain relative paths which
leads to software breaking.  I've tracked it down to AS_SET_CATFILE that
contains code that used to be in _AC_SRCPATHS in 2.57.  With the move the
code was changed not to do a `cd <dir>; pwd' sequence anymore so if a
relative path is passed as input, a relative one is output as well.

 Here is a proposed fix -- the sequence as above is restored, after 
assuring the directory exists.  Please apply.

        * lib/m4sugar/m4sh.m4 (AS_SET_CATFILE): Create the handled 
        directory and change to it to retrieve its absolute path.
