Sandra Loosemore c4c6140463 Add a dummy interrupt handler to nios2 crt0.s. 
The location of the handler at offset 0x20 from the start of memory,
immediately after the 32-byte reset vector, matches the expectations
of real hardware (e.g., a 3c120 board).

    Add semihosting documentation for nios2 and m68k.

    QEMU maintainers have asked for a specification of the nios2
    semihosting interface.  Since it's essentially a copy of the m68k
    implementation, this patch adds a document for that target as well.
