description:
Revive entrypoint heuristics, accidentally removed in the previous.

Now, e.g., "b main" works again for "gdb /bin/echo" as expected.

See more details:
http://cvsweb.netbsd.org/bsdweb.cgi/src/external/gpl3/gdb/dist/gdb/alpha-tdep.c#rev1.2

XXX
Single-stepping into shared libraries still fails sometimes;
tracee does not stop at a function in shared library.
We need further analysis...
