Certain older implementations of mkdir.
>Description:
AS_MKDIR_P in m4sugar/m4sh.m4 has two problems/issues:
1) _AS_MKDIR_P_PREPARE behaves incorrectly on some platforms (such as NextStep
and OpenStep) for which `mkdir' does not recognize any options. The existing
implementation leaves a bogus directory named "-p" sitting in the working
directory.
2) _AS_MKDIR_P_PREPARE neglects to take advantage of the older `mkdirs'
command (note the plural) which exists on some platforms (such as NextStep and
OpenStep), and which performs the same functions as `mkdir -p'.
>How-To-Repeat:
Run any configure script created by 2.57 on a platform with an old mkdir
command.
>Fix:
This patch corrects problem #1 by removing the bogus "-p" directory if
present, and corrects the #2 shortcoming by adding a check for `mkdirs' if
`mkdir -p' fails.
