I am seeing in the RSB log this ...

+ pwd
+ 
build_top=/home/mritunjay/development/rtems/rsb/rtems/build/ptpd-2.3.1-sparc-rtems5-1
+ test x86_64-linux-gnu != sparc-rtems5
+ test -z  -o sparc-rtems5 ==
/home/mritunjay/development/rtems/rsb/rtems/build/ptpd-2.3.1-sparc-rtems5-1/do-build: 
102: test: sparc-rtems5: unexpected operator

Is there a shell script error here?

It is not clear to me why this error did not stop the build?

Please add --trace to the RSB command line. It does create lots of 
output but it does help debug these things.

This looks like a Canadian Cross compile and this does not seem right. 
It may be related to the shell script error above.
