[PATCH, LD, AArch64] Fix ifunc testisms
...
This patch fixes some ifunc testisms after H.J. Lu's patch to enable the
use of IFUNC pointers in position dependent code for binutils. See PR
LD/23169 in binutils bugzilla.
The aarch64 ifunc error message test was changed to no longer expect
this error message as this is now an accepted combination. This patch
also disables the executable tests added by H.J. Lu for aarch64, just as
Alan Modra did with his patch, as these tests only seem to work on some
architectures.
ld/ChangeLog:
2018-07-19 Andre Vieira <andre.simoesdiasvieira@arm.com>
* testsuite/ld-aarch64/ifunc-9.d: Remove no longer expected error.
* testsuite/ld-ifunc/ifunc.exp: Disable tests for aarch64.

aarch64: Add support for GNU indirect functions.

Add support for STT_GNU_IFUNC symbols to the AArch64 bfd backend. The tests
are ported from the ld-ifunc tests but are enabled for cross builds so can
be run easily without hardware or a simulator.
