Tulio Magno Quites Machado Filho 8cc3bcf263 Enable PIC even for static libraries 
Start using CMAKE_POSITION_INDEPENDENT_CODE=ON in order to keep the same
behavior that existed before a set of changes modified it and ended up
with the inclusion of CMAKE_POSITION_INDEPENDENT_CODE in commit
a6e5563dfaff0cb7147058b9c49e38b611a28fb1.

%description
LLVM libunwind is an implementation of the interface defined by the HP libunwind
project. It was contributed Apple as a way to enable clang++ to port to
platforms that do not have a system unwinder. It is intended to be a small and
fast implementation of the ABI, leaving off some features of HP's libunwind
that never materialized (e.g. remote unwinding).
