[Buildroot] Error building "host-uboot-tools" for imx93frdm with latest master

[Robert P. J. Day]

  After resetting my buildroot checkout, pulling master and once
again:

  $ make freescale_imx93frdm_defconfig

it appears that that recent patch related to host-uboot-tools is not
playing nicely with my build:

$ make host-uboot-tools
