 tcgetattr and tcsetattr read shown expected behavior (see Example Code).

 == target hardware
 TMS570 with bugfixes see Bug #3789

 == toolchain version
 Modified GCC, binutils and gdb build script to build armeb compiler build
 with RTEMS Source Builder master(see patches for RTEMS Soucre Builder)
 I need a ARM Compiler with Big Endian Support as default for TMS570 see
 Bug #3789
