Add an elf-dumper utility.

- Output format and some of the code stolen from macho-dump.
- Somewhat incomplete and probably buggy.
- Comes with a very basic test.

Get rid of the last use of -m64 in FrontendC.  This solution
of checking for either 4 or 8 is not very satisfactory, but
it would catch the original problem (an alignment of 1).
