Summary 0001406: ARM: gcc is not configured for the ARM cpu selected in the menuconfig
Description The CPU selected in the menuconfig is not used to configure the gcc build to use the configured CPU. This causes code to be built that will not run on the target due to instructions that can never be executed.

If the cpu type is not specified, then not only is the compiler producing builds of packages that are incorrect, but it will also produce an libgcc with invalid instructions in it.

Passing CFLAGS with -mcpu=<configured-cpu> to the package builds was considered as a posibility, but this will not ensure that libgcc is built with the correct architecture flags.
