bug#66355: guix_defconfig options cannot be overridden in customize-linux function

[Nathan Dehnel]

  (let ((linux-package
         (customize-linux
          #:name name
          #:linux linux
;;          #:configs
;;                        '("CONFIG_FRAMEBUFFER_CONSOLE_ROTATION=y"
;;                          "CONFIG_DMA_PERNUMA_CMA=y"
;;                          "CONFIG_FONTS=y"
;;                          "CONFIG_FONT_8x16=y"
;;                          "CONFIG_FONT_SUN12x22=y"
;;                          "CONFIG_FONT_TER16x32=y")
          #:defconfig
          ;; this defconfig contains the config options above (among others)
          (local-file "defconfig-6.6")

#:configs and #:defconfig both cause this error:

Mismatching configurations in .config and
arch/arm64/configs/guix_defconfig
(("CONFIG_FRAMEBUFFER_CONSOLE_ROTATION" (#f "y")) ("CONFIG_DM
A_PERNUMA_CMA" (#f "y")) ("CONFIG_FONTS" (#f "y")) ("CONFIG_FONT_8x16"
