This presents misleading and confusing output. If you have a function
defined at the beginning of an XCOFF object file, and you have a
function call to an external function, the function call disassembles as
a branch to the local function. That is,
`void f() { f(); g();}`
disassembles as
>00000000 <.f>:
0: 7c 08 02 a6 mflr 0
4: 94 21 ff c0 stwu 1, -64(1)
8: 90 01 00 48 stw 0, 72(1)
c: 4b ff ff f5 bl 0x0 <.f>
10: 4b ff ff f1 bl 0x0 <.f>
With this PR, the second call will display:
`10: 4b ff ff f1 bl 0x0 <.g> `
Using -r can help, but you still get the confusing output:
>10: 4b ff ff f1 bl 0x0 <.f>
00000010: R_RBR .g
