--- Comment #8 from Brandon Maier <brandon.maier@rockwellcollins.com> ---
We just ran into this same build error on one of our boards.

I was able to recreate the error on master
(f30eec41f95ed99909eb2c7590d83c12b9142df2) by building the beaglebone_defconfig
with BR2_TOOLCHAIN_BUILDROOT_USE_SSP=y and BR2_SSP_ALL=y. Then doing "make
valgrind".

The cause is Valgrind requires -fno-stack-protector to build correctly. I fixed
the error by appending -fno-stack-protector to the CFLAGS passed to Valgrind,
so that it overrides the ones in TARGET_CFLAGS.
