BYTE(0) is only for preventing the linker from removing the section.
All we want from the linker is a slot for .got in the section table, and
the actual property (including size) will be filled at runtime by
module_frob_arch_sections. The first GOT entry won't be "appended"
after one byte, it is wrote into the start of .got (at runtime).
