Dimitry Andric 7ecd99fa42 Build compiler-rt against libunwind, not libcxxrt
Parts of compiler-rt are also built for libgcc_eh and libgcc_s, and
these were already pointing to the libunwind unwind.h. For the sake of
consistency, also build compiler-rt itself against the libunwind
unwind.h, not the libcxxrt one.
