package/rustc: add support for ARMv8 with 32-bit software

Browse Source 
BR2_PACKAGE_HOST_RUSTC_TARGET_ARCH_SUPPORTS is not enabled when ARMv8
target hardware is combined with 32-bit software. That is because ARMv7
(32-bit) toolchain is only enabled for BR2_ARM_CPU_ARMV7A which is
mutually exclusive with BR2_ARM_CPU_ARMV8A.

Use ARMv7 toolchain for 32-bit software.
