Linux/AM3352: LTP-DDT installation issues

Part Number: AM3352

Tool/software: Linux

Trying to run LTP-DDT on a custom AM3352 board. (http://processors.wiki.ti.com/index.php/LTP-DDT

I have cross-compiled it as per instructions.

I have used "make install" to get all the target-specific files copied to a output folder, that I then deploy to my target hardware.

I'm able to run the "standard" tests, e.g. "timers",  "mm", "syscalls" via  "./runltp -f timers" 

However, if I try to run any of the TI-specific tests under "ddt", I get an error indicating that some script or binary is missing. 

E.g. "runltp -f ddt/lmbench"  yields the output below, which says I don't have "lmbench_tests_script.sh" installed.      I get similar results with other tests (e.g. ddt/uart complains about serialcheck.sh missing)

I can find the missing scripts inside the ltp-ddt source tree. 

However, these scripts are not present in the output that "make install" produces.

What am I doing wrong?
