[PATCH 01/19] elf: Use memcmp to make suitable for PBL

[Sascha Hauer <s.hauer@pengutronix.de>]

In preparation of adding ELF support to the PBL use memcmp rather than
strncmp for checking against the ELF magic. The other possibility would
be to add strncmp to the PBL, but for the sake of binary size use a
function that is already there.
