Adding to David Given's response, which is great, this is what I use at the end of Android.mk to rename the binary automatically. May be of some use to others trying the same thing:

...
LOCAL_MODULE := yourbinarynamehere

include $(BUILD_EXECUTABLE)

all: $(LOCAL_MODULE)
    $(shell (mv libs/$(TARGET_ARCH_ABI)/$< libs/$(TARGET_ARCH_ABI)/lib$<.so))

Mind the TAB before $(shell... spaces won't work as per standard GNU Make.
