libavutil/arm/asm.S sets '.arch' depending on HAVE_ARMV5TE so that assembling armv5te code will always succeed even if the default -march flag does not support it. HAVE_ARMV5TE_EXTERNAL tests assembling code with the default arch. Fixes the missing symbol ff_prefetch_arm with --cpu= not including armv5te. CC: libav-stable@libav.org
