[Patch] Add .size directives to x86_64 start.S, and possibly more

[Sterling Augustine]

Hello,

sysdeps/x86_64/start.S doesn't have a .size elf directive for _start.
This tripped up some analysis I was doing.

This patch is the straightforward fix. Would you be interested in a
similar fix for the ~150 assembly files inside x86_64 with similar
issues?
