armv8: prevent using THUMB
The predominantely 32-bit ARM targets try to compile the SPL in Thumb
mode to reduce code size.
The 64-bit AArch64 instruction set does not know an alternative, concise
encoding, so the Thumb build option should only be set for 32-bit
targets.
Likewise -marm machine options are only valid for ARMv7 targets.
