Seems reasonable to me, so:
 Reviewed-by: Alan Coopersmith <alan.coopersmith at oracle.com>

though I've been wondering if we shouldn't just have the script
call mkdir -p on modern systems.   (We stopped shipping mkdirheir
for a bit, but got complaints about old Makefiles that stopped
working and since it appears to be in most distros still, and
has almost no maintenance cost, didn't seem worth arguing over.)

AC_PROG_MKDIR_P checks if we can call mkdir -p, but I don't see
a good way to check its result.
