[Buildroot] [PATCH next 1/3] configs/aarch64_efi: switch to external toolchain

[Julien Olivain via buildroot]

This commit switches the aarch64_efi_defconfig to an external glibc
stable Bootlin toolchain, to follow recommendation from [1].

Since an external toolchain is used, the linux-headers.hash custom
hash file is no longer needed and is removed.

Hi Julien,

Thanks for refreshing aarch64-efi.

I verified that this patch series does indeed work fine on Compulab
IOT-GATE-iMX8 (eMMC), ROCKPro64 (SD card), Qemu virt, Qemu SBSA and FVP Base
RevC.

Feel free to add (or not):

Best regards,
