Thomas Petazzoni 141358d838 toolchain-external-linaro-{arm,armeb}: allow on ARMv8 
The Linaro toolchains are currently only available on ARMv7-A, but can
in fact also be used to generate 32 bits code for ARMv8 platforms. This
commit therefore adjusts their architecture dependency.

Example, a 32 bits ARM build produces a 32 bits busybox binary:

$ file output/target/bin/busybox
output/target/bin/busybox: setuid ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 2.6.32, BuildID[sha1]=16a7a70eb9cac08759e52a260478b9c287f59238, stripped

Which was built for Cortex-A72:

$ ./output/host/usr/bin/arm-linux-gnueabihf-readelf -A output/target/bin/busybox
