+ <para><option>android-emulator-no-hw-tls</option>: some

+ <para><option>android-gpu-sgx5xx</option>: use this to
+ support handling of proprietary ioctls for the PowerVR SGX
+ 5XX series of GPUs on Android devices. Failure to select
+ this does not cause stability problems, but may cause
+ Memcheck to report false errors after the program performs
+ GPU-specific ioctls.
