Direct unconditional branches, including procedure calls, can only
reach +/- 32MB from the address of the branch on powerpc.  So if the
image grows to more than 32MB of text there is a problem unless the
linker is smart enough to insert trampolines.  I don't know whether
GNU ld is that smart.  I'm cc'ing Alan Modra who would know the answer
to that.
