use DRIVEROPTS=<options> to pass the following options:
-q, --quiet         Disable same-line progress output (default if stdout is
                    not a tty).
-p, --percentage    Add percentage to default same-line progress output.
-v, --verbose       Print one line per test and minimal extra information on
                    failure.
-vv                 Print all compiler and test output.
-k, --keep-failed   Keep executables of failed tests.
--sim <executable>  Path to an executable that is prepended to the test
                    execution binary (default: the value of
                    GCC_TEST_SIMULATOR).
--timeout-factor <x>
                    Multiply the default timeout with x.
-x, --run-expensive Compile and run tests marked as expensive (default:
                    true if GCC_TEST_RUN_EXPENSIVE is set, false otherwise).
-o <pattern>, --only <pattern>
                    Compile and run only tests matching the given pattern.

use TESTFLAGS=<flags> to pass additional compiler flags
