Basically all platforms have a proper "mkdir -p". Autoconf has install-sh as fallback when using AC_PROG_MKDIR_P, which is also hardened against races if it is recent enough. Update that script and use MKDIR_P whereever possible.

Subject: [PATCH 2/2] use AC_PROG_MKDIR_P to get "mkdir -p" or substitute
Update install-sh to the version from autoconf 1.15, versions prior to 1.10 are
documented to have race conditions. Since MKDIR_P is fine with both existing
target directories as well as "-m" remove some workarounds.
Since I don't know what Cygwin offers I kept mkinstalldirs for the moment, but
already changed the Cygwin makefile to use MKDIR_P. If Cygwin has a proper
"mkdir -p" this could also be used there and mkinstalldirs can be removed.
