Parallel make problem with git master

I am seeing the following compile problem with gmake -j2:

/bin/sh ../../../config/install-sh -c -d '/usr/local/pgsql/lib'
/bin/sh ../../../../config/install-sh -c -m 644 ./plpgsql.control '/usr/local/pgsql/share/extension'

This only happens with parallel gmake and I think is caused by the
assumption that "mkdir extension" will happen before any files are
installed, which doesn't happen with parallel gmake.

I have fixed the bug with the attached, applied patch which moves
'installdirs' to a dependency of the extension directory file install,
rather than a more top-level target so the parallel gmake always creates
the directory first.
