kernel.bbclass: set LD in KERNEL_CONFIG_COMMAND to fix 5.4+ builds when gold is enabled
* with 5.4 kernel the do_configure fails when gold is enabled (with ld-is-gold in DISTRO_FEATURES)
* bfd is already being set in KERNEL_LD:
kernel-arch.bbclass:KERNEL_LD = "${CCACHE}${HOST_PREFIX}ld.bfd ${HOST_LD_KERNEL_ARCH}"
but KERNEL_LD is currently respected only by do_compile and do_compile_kernel modules
and new kernel which contains a check for gold in Kbuild:
https://lore.kernel.org/lkml/alpine.DEB.2.21.
1907161434260.1767@nanos.tec.linutronix.de/

will fail during the configuration even when gold wouldn't be used to
build it in the end, add LD setting to KERNEL_CONFIG_COMMAND to prevent
premature error when configuring
