Try first ./staprun to see if "help" is coming out. "printf" shall work ! Try to chmod staprun and stapio, this does not look related to systemtap
I made systemtap work on Froyo and Gingerbread, well this is essentially a kernel related tool on ARM (no time to investigate/code utrace/uprobes on our side :-( ) so it shall work on any pastry, as google does not change that much the kernel. But userspace is killing me as a developer.

Mmmmh, we have hit issues when running several scripts in parallel (on Android, works fine on Ubuntu). Works first time, not 2nd time. Or issues when probing all system calls. But iotop.stp is working fine on my Gingerbread (K2.6.35)

We are at kernel 2.6.35. I don't really track the potential incompabilities between kernels and systemtap. We had to modify ptrace.h in the past, I don't remember when we started no longer needing it

You don't need an OMAP platform. We don't make any specific change for OMAP. Using /data/staphome instead of /home/xxx is totally OK as far as you respect paths on desktop and target, which is the case for you.
