pseudo 1.4.2: linkat() and bitrot cleanup

The major change here is the addition of linkat(), and the change of link() to be written in terms of it (for consistency with othe *at() calls).

I checked this out on Darwin (which hasn't got *at() functions) and picked off a couple little bits of bitrot.

The other change is that the WR build system turns out to have reasons to, in some cases, actually use a lib64 directory for things like the host sqlite3 library. So I cleaned up the computation of the sqlite library path; of course, this then broke oe-core on 64-bit hosts, but I'd anticipated that, and pseudo's configure can take an explicit full path to libsqlite3.a if it's not in a directory with the same name as $(LIB). Did that to the various 32-bit and 64-bit forms. Note that on 64-bit hosts, this means that 32-bit libpseudo (if it's being built) is being configured with the explicit path to our 64-bit libsqlite3.a; that's okay, because we only build libpseudo for the 32-bit case. Confirmed that, with NO32LIBS = 0, I get both 32-bit and 64-bit libpseudo.

I did have build failures in perl-native when I was first testing this, but updating oe-core made them go away, so it was probably just my tree being pretty old before I started on the pull request.

The tarball is already on yoctoproject.org (thanks, pidge!) and I have verified that the build still succeeds.
