For me _GLOBAL_OFFSET_TABLE_ is only a linker symbol. It will not be 
present in the GOT. I don't understand why setting its value to "." would 
not be taken into account (maybe is it a special symbol ?). And I don't 
see any semantic difference between the 2 linker scripts, so that I'm a 
bit confused they are interpreted differently.

As a side note, this script also fails to work as I would expect (but I'm 
not an expert on this) :

SECTIONS {
        /DISCARD/ : {
                *(.stab*)
                *(.comment)
                *(.note)
        }
        _GLOBAL_OFFSET_TABLE_ = .;
        all : {*(.got, .text, .rodata, .rdata, .data, .bss) }
}
