[mc] Support DWARF4 DW_FORM_sec_offset (found in libpthread_nonshared.a)

Add support to DWARF4 DW_FORM_sec_offset in order to handle DWARF4
libpthread_nonshared.a.

We do not yet handle DWARF3 and 4 but only DWARF2. It is not a big
problem as it is possible to ask GCC to generate DWARF2 with:
-gdwarf-2.

However, even with this option, some static/non-shared libraries might
be included such as libpthread_nonshared.a which might be compiled
with DWARF4 information. This happen in Debian testing (2014-03-06).
