2017-12-14 Steve Ellcey <sellcey@cavium.com>
* Makefile.am (IFUNC_OPTIONS): Change aarch64
option from -march=armv8.1-a to -march=armv8-a+lse.
* configure.ac (*aarch64*): Check to see if
compiler understands -march=armv8-a+lse option.
* configure.tgt (*aarch64*): Only set try_ifunc
if compiler understands -march=armv8-a+lse option.
* Makefile.in: Regenerate.
* testsuite/Makefile.in: Regenerate.
* configure: Regenerate.
* aclocal.m4: Regenerate.
