Bring in 2 patches from binutils:
...
From Alan Modra: Wed, 3 Jul 2013 11:51:56 +0930: powerpc64 call stubs:
This brings powerpc64 ld in line with gold regarding calls allowed to
go via a plt call stub or toc-adjusting stub without a following nop.
A long time ago ld allowed tail calls, but this is wrong because we'll
return to the caller's caller with the wrong toc pointer. I fixed
that for shared libraries but allowed tail calls in an executable for
some reason. Probably just muddy thinking on my part, because there's
no difference between an executable and a shared library regarding the
need to restore the toc pointer. Perhaps it was because some testcase
failed, most likely due to the g++ issue I comment on in the patch.
From Alan Modra: 29 Aug 2014 01:22:29 +0000: PowerPC64 call lacks nop error:
Enough people accidentally or otherwise use -mcmodel=small then wonder
why a call that is local is behaving as if it is going via the PLT.
* elf64-ppc.c (ppc64_elf_relocate_section): Report a different
error for calls via a toc adjusting stub without a nop.
