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. base/loader/elf_object.hh: - Use program header instead of section headers for loading.
