The coremark binary includes a copy of the compiler flags in the output
which breaks the reproducible build tenet of Yocto. This patch simply
replaces COMPILER_FLAGS with "".
This is also needed on scarthgap, where it is a warning, not an error, but
still.
Agreed.

+Reproducible builds do not like including anything that references the
