GCC 8.1's linker tries to rewrite the code to match the lowest common denominator, reintroducing references to __aeabi_idivmod and friends even on ARM revisions that don't need them. Tell it what it's linking for to keep it harmless. BUG=b:65441143 BRANCH=none TEST=make buildall works with gcc 8.1 Change-Id: I7296aa80f587aa4f004fb20958714766793ab2b5 Signed-off-by: Patrick Georgi <pgeorgi@google.com> Reviewed-on: https://chromium-review.googlesource.com/1061693 Commit-Ready: Patrick Georgi <pgeorgi@chromium.org> Tested-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-by: Stefan Reinauer <reinauer@google.com>
