Can you compile a "hello world" program with your toolchain and run it
successfully on your box?

#include <stdio.h>
int main(void)
{
    print("Hello, world!\n");
    return 0;
}

If no - then you have an underlying toolchain or platform problem which is
nothing to do with asterisk.

If yes - then maybe you should try getting gdbserver to run on your
platform, so that you can run gdb on the host and asterisk under it on the
target system. I have had this working with OpenWrt (using MIPS not ARM).

It's probably an extremely useful thing for you to have anyway. Or if you
can get a coredump from asterisk, and copy it back to the host, you can use
gdb to analyse it there (see same URL)

Finally - have you tried adding a printf() at the start of asterisk's main()
to see if it's getting there?
