What about those of us who have been using crossdev to generate
cross-compilers for years w/o issue, because we run non-multilib?
Hardmasking crossdev to solve multilib problems doesn't accomplish anything,
other than just irk us.  Why not hardmask the multilib stuff instead and
leave crossdev alone?

Neither hardmask solution is viable, since you'll inconvenience one side for
the sake of the other.  That's not how you solve problems.

Is my understanding of the issue correct, in that, per Bug #500338, crossdev
was used to merge an i686-pc-linux-gnu cross-toolchain onto an
x86_64-pc-linux-gnu system, resulting in /usr/bin/cross-pkg-config being
linked to /usr/bin/i686-pc-linux-gnu-pkg-config, which causes the problem
reported in that bug?

If so, is it sensible to allow crossdev to install a cross-toolchain when
the underlying machine architecture is the same, just a different ABI?
I.e., would a solution be to prevent i686-on-x86_64 or mips64-on-mips, but
still allow mips64-on-x86_64, and such?
