Without this change statically linked binaries will almost certainly have
unparsable .eh_frame contents since the DW_EH_PE_absptr values used here
will not be capability aligned, so libunwind will trigger an alignment
fault calling getEncodedP(p, cieContentEnd, cieInfo->personalityEncoding).
For some reason I only saw this crash (while hanlding a C++ exception) in binaries built with LTO, not normal ones, but that's probably just caused by getting lucky on the alignment.
TODO: this needs a test case before merging
