Ben Gras b029fb598a new libunwind, updated to netbsd b1f513eedd
existing libunwind used '0' in lsda_encoding as 'not present,'
whereas that is a valid encoding and does occur and would be
ignored. a missing encoding is actually 0xff.

The commit that addresses this is:

commit 8d4b51028d1a12b58d616f4b605254a877caafcf
Author: joerg <joerg>
Date:   Tue Mar 11 23:52:17 2014 +0000

    0 is a valid LSDA encoding and can be seen in statically linked
    programs. Initialize lsdaEncoding to DW_EH_PE_omit and check for that
    value to decide whether a value should be decoded.

more bugfixes are necessary. this update is up to:

commit b1f513eedd332426d88acbb118b6e9070966dcb9
Author: joerg <joerg>

    Lazy VFP processing works a lot better if the functions contain a return
    instruction.
