Subject: [PATCH] rustc: put targetPrefix in pname

Our rustc package is not universal, because we only build std for the
host and target platforms.  This means that a build graph where cross
is involved will end up with multiple rustc packages in it, so it
would be helpful to have a way to tell them apart, just like we do for
e.g. gcc.
