r269092: Improve section type reporting
The SHT range 0x70000000-0x7fffffff is processor-specific. Pass the
ELF machine type header to sh_types so the section header type name can
be reported correctly for the given processor.
For all ranges report the actual value for unknown types.
Add MIPS-specific type SHT_MIPS_OPTIONS.
r269143 (andreast): Further improvements on elfdump, to follow up r269092:
- Add ARM specific section header types.
- Add SHT_GNU_HASH section header type.
- Improve reporting of undefined tags in d_tags.
- Add DT_GNU_HASH tag.

r270303: Rename DT_FEATURE_1 to DT_FEATURE
This provides a minor cleanup in elfdump; there are otherwise no
consumers in the tree. Old SUN documentation can be found for either
variant, but GNU binutils switched to DT_FEATURE around 2000.
