Its compensating for the old gcc bugs where gcc "i686" generated cmov
instructions without any checks whether the CPU supported cmov (which is
optional for a 686 architecture)

RPM has (or had) similar hacks. Both arguably come about from fundamental
design thinkos in that they treat architecture as "special", not simply
as a set of dependancies (needs x86, x86-cmov, glibc x86-32, ...) as
should hve been done and which would also have made emulators just work
out of the box instead of the current mess.
