There shouldn't be a need to clear the caches unless you've changed
the specs or sources.  Presumably you had to change something to fix
whatever killed stage1.  If that was an ebuild problem, it's unlikely
that your fix changed an ABI without also changing the package version
and you should be ok keeping the old binary packages.

Disabling creation of binary packages during the seed stage update
would help, and disabling the use of binary packages during the stage1
build would help.  However, what if you have built a binary package
for GCC and then you update your tree to something that builds
libmpc.so.3.  In this case, you're in trouble if you use your old GCC
binary packages anywhere based on the new tree.
