This is current/armv7 on BeagleBone Black, or almost current:

I don't know much about instruction sets on the various platforms,
but I see the following in the Makefile:
.if ${MACHINE_ARCH} == "arm"
CONFIGURE_ARGS+=--enable-fixed-point
.endif
Can that be it? The configure has detected
Floating point support: ........ no
Fast float approximations: ..... no
so isn't it using fixed-point already?
I am running it now with "armv7" added,
but it's gonna take a while on the BBB.
