base/loader/elf_object.cc:
- Use program header instead of section headers for loading.
The old code doesn't work for Alpha/Linux user binaries.
- Deal properly with single-segment ELF executables (e.g. kernels)...
haven't tested this but it looks like it matches the functionality
of the patch the L4::Pistachio guys sent.
- Factor load symbol code into one common function.
- Some formatting to match style conventions.
- Only include libelf stuff in .cc file, not .hh.
