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
