Makefile.inc: Avoid race condition when using 'make -j<N>'
When building coreboot from scratch with 'make -j4', I sometimes see
this error:
CREATE build/mainboard/emulation/qemu-riscv/cbfs-file.wblRgZ.out (from /.../coreboot/.config)
HOSTCC cbfstool/cbfstool (link)
make[1]: execvp: build/util/kconfig/conf: Permission denied
make[1]: *** [/.../coreboot/util/kconfig/Makefile:92: savedefconfig] Error 127
It happens, I think, because the rule generated by
cbfs-files-processor-defconfig runs 'make savedefconfig', which builds
build/util/kconfig/conf, and something also builds it, at the same time.
Fix this case, by making this rule depend on $(objutil)/kconfig/conf.
The same fix is also precautiously applied to the rule for
$(KCONFIG_AUTOHEADER) in Makefile.
