Mischa Jonker 381654d8a8 arc: gcc: Go from 4.4.7 to 4.8 for ARC
This fixes multiple issues, including:
 - 'operand out of range' errors (due to defaulting to
   medium calls instead of short calls)
 - library dependencies that were not being found

arc: Fix operand-out-of-range errors
brcc_s instructions can generate operand-out-of-range errors. While a
better solution is being discussed by the compiler team, this workaround
ensures that the chances of running into this issue are low.
