Hmm, depends, from a general viewpoint I'd say no, but....
If that library don't use any systemcalls directly, but only accesses
them through libc, and we have them in our libc, it might work.
Otherwise its a sure failuremode, as one binary can only have one
systemcall structure (sysentvec), and there is no easy way to change
that.
