The test results are not that bad. Some tests use files, which are not 
available to the RTEMS test driver. The main issues are due to thread 
cancel/exit misbehaviour of RTEMS. Shared mutexes are not implemented in 
general.

Target is arm-unknown-rtems4.11
Host   is arm-unknown-rtems4.11
Build  is x86_64-pc-linux-gnu
