This bug is probably lurking there for so long, I cannot even git-blame my way to the commit first introducing it. Anyway, because n32 is also TARGET_MIPS64, the address space range cannot be determined by looking at TARGET_MIPS64 alone. Fix this by only declaring 48-bit address spaces for n64, or the n32 user emulation will happily hand out memory ranges beyond the 31-bit limit and crash. Confirmed to make the minimal reproducing example in the linked issue behave.
