GOT stands for global object table. I *think* it is generated by
compiler for PIC code and needs to be filled out during loading
time (i.e., during run-time linking time).
For FLAT format executables, the loader is inside kernel. Check
fs/binfmt_flat.c file. I believe somewhere there it is creating
the GOT section and filling proper contents into the table.
Cheers.
