ecbe6b9f7f [dev.power64] runtime: replace getproccount with simpler code 
This runs once. There is no need for inscrutable algorithms.
Also it doesn't compile correctly with 9c.

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.

main thing is the use of the new flag parser.
