c6x: handle c6x unk_isa in TARGET_CPU_CPP_BUILTINS

Fixes all-gcc for c6x config-list.mk that complained about

error: enumeration value ‘unk_isa’ not handled in switch

Maybe seeing unk_isa in the cpu switch statement should
__builtin_abort() but be conservative to just allow all-gcc of config-list.mk
to compile
