Subject: Patch from Stefan Allius:

    Hi Erik,

    I patched the initfini.awk script, so we can build crt[in].S for the SuperH
    targets with gmon-support.

    The patch moves all labels into the wright sections, and add some assembler
    statements to jump over them. (only activ on SH targets)

    The patch also avoid any references of _GLOBAL_OFFSET_TABLE_ or *gmon_start*
    in the crtn.S file. This should work on every target.

    Bye Stefan
