eh_frame_parser is architecture independent, thus the files have
been rearchitectured. Some bugs have been fixed in the test.
A README file has also been added to eh_frame_parser host test
directory.
eh_frame_parser is now able to detect empty gaps in .eh_frame_hdr
table (missing DWARF information).
Fix a bug occuring when parsing backtraces originated from abort().
Fix build missing dependencies issue.
