PRU architecture supports maximum 256k program memory (IMEM). Some GCC
test cases manage to produce executables bigger than that.

gcc/testsuite/ChangeLog:

2018-10-08  Dimitar Dimitrov  <dimitar@dinux.eu>

	* lib/gcc-dg.exp: Bail on region overflow for tiny targets.
	* lib/target-utils.exp: Ditto.
	* lib/target-supports.exp: Declare PRU target as tiny.

Signed-off-by: Dimitar Dimitrov <dimitar@dinux.eu>
