riku.voipio@linaro.org - April 6, 2012, 4:35 p.m.
From: Peter Maydell <peter.maydell@linaro.org>

Update the EF_ARM_* constants (for the ELF header e_flags field)
to include the newer flags specified for later versions of the ABI.
(This set of constants is from include/elf/arm.h from binutils-2.17
and so licensed under GPL-v2-or-later.)
