Add initial arm64 support

Based on a working config by Paul Whalen. The generated config ends
up being the same, so hopefully this marks the first ARMv8 Fedora
kernel.

+- ARM64 support (config-arm64)
+  Split out some config-armv7-generic options common between 32-bit and 64-bit
+  ARM into a new config-arm-generic, and use that as a base for
+  both.
+  Buildable in rawhide, and F-19 by installing {gcc,binutils}-aarch64-linux-gnu
+  and running:
+  rpmbuild --rebuild --target $ARCH --with cross --without perf \
+    --without tools --without debuginfo --define "_arch aarch64" \
+    --define "_build_arch aarch64" \
+    --define "__strip /usr/bin/aarch64-linux-gnu-strip" kernel*.src.rpm
+  As rpm in F-19 doesn't have aarch64-linux macros yet.

 - Introduce infrastructure for cross-compiling Fedora kernels. Intended to
   assist building for secondary architectures like ppc64, s390x, and arm.
   To use, create an .src.rpm using "fedpkg srpm" and then run
-  "rpmbuild --rebuild --with cross --without perf --without tools \
+  "rpmbuild --rebuild --target t --with cross --without perf --without tools \
     kernel*.src.rpm" to cross compile. This requires binutils and gcc
   packages named like %_target_cpu, which all but powerpc64 currently provides
   in rawhide/F-19. Can't (currently) cross compile perf or kernel-tools, since
