parisc64 currently does not define -mdisable-fpregs, so the kernel is
using fp regs to do multiplication rather than calling millicode ($$mulI)
to do it.  Unfortunately, there's no $$mulI routine available for 64-bit
so we need to create one (64-bit libgcc?) before we can enable this flag.
Grant claims Paul knows what to do.

One point in favour of merging parisc & parisc64 is that i found this
bug which could've caused a lot of head-scratching later.
