Michael J. Spencer 67bc8d6b3f [elf2] Add basic relocation support for x86-64. 
This currently doesn't handle local symbols.

Rafael Espindola c5c82916e4 Read the alignment only when used. 
The rest of the header was already read lazily, no point in having align be
special.

Rafael Espindola 674b5d570f Store the offset in the output section, no in the file. 
That is the value that is stable as the we layout the output sections.

Rafael Espindola e7a00e326a For now we only have on Chunk type. Simplify. 
The others we have in sight are
* common symbols.
* entries in SHF_MERGE sections.

They will have a substantially different treatment. It is not clear if it is
worth it putting them all in a single list just to dispatch based on the kind on
the other side.

I hope to implement common symbols soon, and then we will be in a position
to have a concrete discussion. For now this is simpler for the the implemented
features.

Michael J. Spencer 8a4145411f Initial ELF port. 
This is a direct port of the new PE/COFF linker to ELF.

It can take a single object file and generate a valid executable that executes at the first byte in the text section.
