This may never work correctly for i386 since its PLT entry uses
%ebx:

000001b0 <address@hidden>:
 1b0:    ff a3 0c 00 00 00        jmp    *0xc(%ebx)
 1b6:    68 00 00 00 00           push   $0x0
 1bb:    e9 e0 ff ff ff           jmp    1a0 <address@hidden>

We can't return pointer to PLT entry since wrong %ebx
may be used when calling it.
