The ARMv7 EABIhf toolchains can currently be selected with ARMv8 cores
selected, even when EABI is used due to how the condition is
constructed. This obviously fails as those toolchains are EABIhf,
causing the following build issue:

Incorrect ABI setting: EABI selected, but toolchain is incompatible

This is for example what happens with:

BR2_arm=y
BR2_cortex_a32=y
BR2_ARM_EABI=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_BOOTLIN_ARMV7_EABIHF_GLIBC_BLEEDING_EDGE=y

In order to address this, we adjust the script generating the Bootlin
toolchain package so that EABIhf is required for both ARMv7 and
ARMv8.

Please note that we already require BR2_arm for those toolchains, so
we are *only* talking about ARMv8 cores being used in 32-bit mode.

This will be needed to fix:
