We had a check using TARGET_VIRT_ADDR_SPACE_BITS to make sure that the allocation coming in from the command-line option was not too large, but that didn't include target-specific knowledge about other restrictions on user-space. Remove several target-specific hacks in linux-user/main.c. For MIPS and Nios, we can replace them with proper adjustments to the respective target's TARGET_VIRT_ADDR_SPACE_BITS definition. For ARM, we had no existing ifdef but I suspect that the current default value of 0xf7000000 was chosen with this in mind. Define a workable value in linux-user/arm/, and also document why the special case is required.
