The irony is that older boxen which would benefit most from building from

I doubt that the bin package will be slower than the one compiled from
source. I predict the reverse, in fact. The bin package will perform
better.
That seems a strange prediction. What drives that hunch?
The PGO optimized build that Mozilla is shipping. You can also build
with PGO from source, but that means building FF *twice* in a row (by
enabling the "pgo" USE flag). I doubt that with the old laptop anyone
is building FF twice with PGO, and that means that the -bin package
should be faster.
Furthermore, FF is build using its own CFLAGS. They are the same in the
source build as well as in the -bin package. The only difference is
probably the -march option. And that doesn't make much difference to
begin with (after -march=i686, gains are very minimal).
