cmd/dist, cmd/link, runtime: fix stack size when cross-compiling aix/ppc64
This commit allows to cross-compiling aix/ppc64. The nosplit limit must
twice as large as on others platforms because of AIX syscalls.
The stack limit, especially stackGuardMultiplier, was set by cmd/dist
during the bootstrap and doesn't depend on GOOS/GOARCH target.
Fixes #29572
