From: Jan Kiszka <jan.kiszka@xxxxxxxxxxx>
Subject: scripts/gdb: add get_target_endianness helper
Parse the target endianness from the output of "show endian" and cache the
result to return it via the new helper get_target_endiannes. We will need
it for reading integers from buffers that contain target memory.
