This patch introduces a check failure. See:
https://gitlab.com/buildroot.org/buildroot/-/jobs/11481238341

WARN: defconfig ./configs/aspeed_ast2500evb_defconfig can't be used:
       Missing: 
BR2_TOOLCHAIN_EXTERNAL_BOOTLIN_ARMV6_EABIHF_GLIBC_STABLE=y

This defconfig does not select any CPU, so it defaults to:
BR2_arm926t=y

According to the Kernel dts:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/arch/arm/boot/dts/aspeed/aspeed-g5.dtsi?h=v6.16.7#n40

Cpu seems to be "arm1176jzf-s".

In that case, this defconfig should add:
BR2_arm1176jzf_s=y

Could you confirm it is the case and send a patch fixing the issue,
please?
