Get TEST_LIBC_STR passing on AARCH64

Browse source 
It's now possible to run commands like:

    make -j8 m=aarch64 o/aarch64/test/libc/str

Which will cross-compile and run the test suites in a qemu-aarch64
binary that's vendored in the third_party/qemu/ folder within your
x86_64 build environment.
