I pulled r19308 (ARM: enable fast_unaligned when --cpu=armv[67] is specified):
--- a/configure
+++ b/configure
@@ -1792,6 +1792,10 @@ if test $cpu != "generic"; then
add_cflags -mcpu=$cpu
enable fast_unaligned
;;
+ armv[67]*)
+ add_cflags -march=$cpu
+ enable fast_unaligned
+ ;;
armv*)
add_cflags -march=$cpu
;;
so it's effectively identical to --cpu=cortex*.
