Use arm_eabi_breakpoint on aarch32

Browse Source 
Nowdays, GDBserver chooses arm breakpoint instructions by checking
macro __ARM_EABI__.  When aarch64 GDBserver debugs arm program,
arm_eabi_breakpoint is still needed, but __ARM_EABI__ isn't defined
in aarch64 compiler.  This causes GDBserver chooses the wrong
breakpoint instruction for arm program.  This patch fixes it.
