So we had a problem, after all: libgcj.spec is to be installed only in
the primary multilib directory.  Nothing else will do.  It's not
searched in multilib subdirectories at all, neither in gcc's multilib
conventions nor in the os's multilib conventions, so I just went ahead
and introduced toolexecmainlibdir in libjava/configure.in and arranged
for libgcj.spec to be installed there.  Multilibs will overwrite each
other's libgcj.spec, but this is not a problem since we've been using
only the libgcj.spec of the default multilib anyway.

I'm checking the following patches in 3.2, 3.3 and mainline,
respectively.  They're only different as far as line numbers go,
except for libiberty in 3.2, that required tweaking since it's not
DESTDIRified there.
