What is the target specification for a ARMv8.2A? I'm trying to build a cross compiler

Are you talking about 32bit arm or aarch64? ARMv8.2A sounds like 64
bits, but Thumb2 sounds like 32 bits.
Armv8 supports both AArch32 (32-bit) and AArch64 (64-bit) execution
states. To generate code for AArch32 you'll need the 'arm'
configurations of GCC. The 'aarch64' configuration can only generate
code for 64-bit state.
