By default, -DNO_TRAMPOLINES is set in testsuite/lib/gcc.exp if the
DejaGnu target info reports that the support doesn't exist. The only
other feature treated this way is no_label_values.

Not for the user to disable them, although tests for these features
check whether the support is available to the target. The procs that
check for the support are check_profiling_available and
check_effective_target_fpic in testsuite/lib/target-supports.exp.
The .exp files for profiling tests call check_profiling_available and
skip the directory if that proc returns 0.
"fpic" is an effective-target keyword that can be used alone or in
combination with other target information to limit when a test is run,
e.g. "{ dg-do run { target fpic } }".
There's no way to disable tests for these features if the procs in
target-supports.exp claim that they are supported. If your target
doesn't support them, you can modify those procs to skip the tests.
