Rafael Espindola a5d43d004a Propagate sh_entsize out. 
No difference in practice other than having sh_entsize in the output.

This should simplify the patch for handling SHF_MERGE in -r.

Based on a patch by George Rimar.

Petr Hosek edd6c3587c [ELF] When the code segment is the last, align it to the page boundary 
When the data segment is the last segment, it is correct to leave
it unaligned. However, when the code segment is the last segment,
it should be aligned to the page boundary to avoid loading the
non-segment parts of the ELF file at the end of the file.

Rui Ueyama 0cc1483562 Add basic 64-bit SPARC support 
Add support for the most common SPARC relocations.
Make DT_PLTGOT point to the PLT on SPARC.
Mark the PLT as executable on SPARC.

This adds a basic test that creates a SPARV9 executable
that invokes the exit system call on OpenBSD.

Patch by Mark Kettenis.
