  Target Milestone: ---

Found in http://www.spinics.net/lists/linux-sh/msg51060.html, a Buildroot
generated toolchain for SH4 fails to build the Linux kernel
magicpanelr2_defconfig:

/opt/cross/kisskb/br-sh4-full-2016.08-613-ge98b4dd/bin/sh4-linux-ld:
kernel/sched/built-in.o: uses dsp instructions while previous modules use
floating point instructions
/opt/cross/kisskb/br-sh4-full-2016.08-613-ge98b4dd/bin/sh4-linux-ld:
kernel/sched/built-in.o: uses instructions which are incompatible with
instructions used in previous modules
/opt/cross/kisskb/br-sh4-full-2016.08-613-ge98b4dd/bin/sh4-linux-ld: failed to
merge target specific data of file kernel/sched/built-in.o
/home/kisskb/slave/src/scripts/Makefile.build:380: recipe for target
'kernel/built-in.o' failed
make[2]: *** [kernel/built-in.o] Error 1

(Note: this is a bug from January 2017, which I notice only now. Before I
forget, I fill in a bug report about it, so we can have a look at it later.)
