Subject: [PATCH] [libunwind] Fix warning when building without frameheader
 cache

Without the fix the compiler warns with

/data/repo/master/libunwind/src/AddressSpace.hpp:436:44: warning: unused parameter 'pinfo_size' [-Wunused-parameter]
                                    size_t pinfo_size, void *data) {
                                           ^
