OK, go ahead and make the substitution.

I can see that in rare, rare cases, since MKDIR_P is a command, people
may want to use different versions of it. But for things like @LIBINTL@
and @LIBSOCKET@, it is still better to write them as @LIBINTL@, not $(LIBINTL),
because if the corresponding autoconf macro was not run, it makes the error
appear on all platforms. Otherwise it's too easy to write a Makefile.am
that builds fine on glibc systems but not on Solaris or MacOS X.
