profiles: allow USE=libunwind for sys-libs/libcxxrt, #589352

We can use -rtlib=compiler-rt to tell clang not to link binaries with libgcc_s.
Re-enabling this flag allows us to build libcxx against libcxxrt and libunwind,
thus having a GCC-free C++ runtime stack.

-# The idea behind using libunwind there is to avoid needing to link to libgcc_s
-# and have a C++ stack without gcc with libcxx.
-# However, in any case, clang links its binaries to libgcc_s, hence at the
-# moment there is not much point in enabling this.
