NetBSD/arm: disable pax mprotect restrictions for emu

ARM has separate read and execute protection bits so after writing out

add AIX/power port

Use explicit -fno-strict-aliasing to be on the safer side of things.

miscompiles at least dtoa.c on powerpc.

mkfile-NetBSD-power - copied and trivially adjusted from the 386 version

Drop space before tab.

Don't add X11 paths to LDFLAGS here. It's only needed for emu and is
provided along with the X11 libs it that mkfile.

NetBSD swtiched to X11R7.
