6e73ae88b5 [dev.power64] cmd/9l, math/big, runtime, syscall: fixes for power64 
On the machine I'm using, the hardware page size seems to be 64 kB.
Make ELF rounding and mmap quantum 64 kB to match.

Error numbers returned from kernel are positive; do not negate.

Implement stubs for math/big.

f285537b7f [dev.power64] cmd/9g: do not ignore move instructions even if from and to are samaddr() 
Those moves might be significant (e.g. narrowing or widening): on Power64,
we don't distinguish between MOVWD and MOVW.

This fixes divmode.go and bug447.go.

53b78c84bc [dev.power64] cmd/9a: use new flag parser 
Copy main from 6a. Fixes various things, but the
main thing is the use of the new flag parser.
The go command expects to be able to use -trimpath
and not have it be interpreted as -t rimpath.
