(_AS_MKDIR_P_PREPARE): New macro.

Browse Source 
(AS_MKDIR_P): Require it.  Use mkdir -p if available, falling
back on AS_DIRNAME to compute prefixes otherwise; this is
roughly what mkinstalldirs does.  That way, we need not have
our own filename disassembler.  The old disassembler did not
work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
