RSB create report error

[Sebastian Huber]

Hello,

I tried to build the latest RTEMS 6 tools via RSB on Linux, but there 
was a failure in GDB. Unfortunately, the report generation failed:

error: building powerpc-rtems6-gdb-4e394b2-x86_64-linux-gnu-1
Build FAILED
error: failure to create error report
