PRU architecture supports maximum 256k program memory (IMEM). Some GCC
test cases manage to produce executables bigger than that.
gcc/testsuite/ChangeLog:
2018-06-13 Dimitar Dimitrov
* 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.
