I don't think so.  If I remember right, -mfloat-abi=softfp is for the
case where you want to use hard floating point instructions (for speed)
but still want to retain compatibility with a soft-float ABI.

I wonder if something has gone wrong with your glibc configuration.  Try
disassembling one of your binaries and see if you can find any reference
to "wfs" or "rfs" instructions.  Also have a look in libc.so.6 itself to
see what the syscall instructions look like: for OABI you will see
something like "swi 0x900004", whereas for EABI it will look more like
"mov ip, r7; mov r7, #4; swi 0; mov r7, ip".

Heh.  True, but only if he finds out :-)
