marcel 448c522a41 Implement the lock with a cmpxchg instruction instead of a xchg.

Both are atomic, but the cmpxchg has memory ordering hints. We
give this acquire semantics.

NOTE: The unlock in libc_r is implemented by a "normal" assign
statement. This is not correct on ia64 due to the memory ordering
characteristics of the architecture. We need release semantics
for an unlock.
