[PATCH] D23420: libcxx: Fix libcxx test on aarch64 with libunwind

Yes, although in pratice for shared libraries this is not an issue (at least on Linux with current linker strategies). And I open for suggestion on how to proceed in this case since we have some other options:

1. Add the required soft-sp implementations when building for Linux (this might happen not only on aarch64, but any other ABI that defines long double using fallback soft-fp)
2. Remove the possible soft-fp usages on all the tests. However this will lead to possible remove *all* the FP cases if libcxx should be used in a pure soft-fp platform
3. Only allows the libcxx + linunwind to be built against compiler-rt
