3.5.11 Function Calls

Programs use the 64-bit PowerPC bl instruction to make direct function calls. The bl instruction must be
followed by a nop instruction.

The definition we currently use for whether a call is interposable doesn't agree with the logic in GNU ld or GCC. While it doesn't matter for inlined functoins, a call must contain the nop as the target can be replaced.
