When I build "core-image-sato-sdk" to run LTP/POSIX test suite, I met some troubles when execute the following command to run POSIX Test suite:
$ bin/run-posix-option-group-test.sh [OPTION-GROUP] (*)
such as:
$ bin/run-posix-option-group-test.sh TMR
$ bin/run-posix-option-group-test.sh AIO
...
Before that, I ran some commands to configured and built POSIX test suite.
$ cd /opt/ltp/testcase/open-posix-testsuite
$ make generate-makefiles
The log message I was received when I ran (*) command is shown at bellow:

****Tests Complete****

===========================================
But, If I used following command, instead of using (*) command:
$ make all test
the log message was:
....

testcases/open_posix_testsuite/conformance/interfaces/pthread_rwlock_rdlock'

....
=> I could run the POSIX Test suite normally.

==========================================
Questions:
Do you know why I could not execute the (*) command to run POSIX Test Suite?
