From the bug report:

It seems that JDK-8198724 "Refactor FLAGS handling in configure" broke the aarch64 build. The new configure scheme tries to pass the argument "-m64" to the gcc compiler, but that is an x86-only flag. configure:35228: checking whether the C compiler works configure:35250: /usr/bin/gcc -m64 -m64 conftest.c >&5 gcc: error: unrecognized command line option '-m64' gcc: error: unrecognized command line option '-m64' [...] The flags handling is currently in flux. The entire "MACHINEFLAG" handling is not optimal. But we can't have aarch64 hanging around broken awaiting a proper refactoring, so here's a not-ideal-but-working patch.
