Subject: Fix creation of build directories with
 non-recursive-gnulib-prefix-hack.

This is necessary for executing "make" in a VPATH build of a package
that uses prefix-gnulib-mk and a module such as alloca-opt.

* modules/alloca-opt (Makefile.am): Before generating the .h-t file,
ensure that the directory in which we want to create it exists.
(configure.ac): Invoke AC_PROG_MKDIR_P.
