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
