build: disable backtrace feature on AArch64 Linux

There are sporadic segfaults in libunwind during backtrace_collect(). Reproducible with the latest version, and there are open issues with similar stacks: libunwind/libunwind#150 libunwind/libunwind#260 libunwind/libunwind#473 Let's disable ENABLE_BACKTRACE for AArch64 Linux until these issues are resolved in libunwind. Closes #8572 Part of #8791 NO_DOC=bugfix (cherry picked from commit 418e749)
