Yes you are right. Thanks.
The function elf_machine_load_address (void) is inlined in _dl_start,
thus (_dl_start - 1b) is negative. If it wouldn´t be inlined and would 
be located after elf_machine_load_address, this is not correct.

But truncating the expression (in this case: 0xffffffff7fffffea) by 
anding it with 0x00000000ffffffff, the resulting value isn´t changed 
regardless of (_dl_start - 1b) is positive or negative, but the 
assembler does not warn about truncating the value.

Bye
Stefan
