More on this: if you put the RTS in

   lib/gcc/arm-eabi/4.7.4/ravenscar-sfp-stm32f4

then gnatls can see it (arm-eabi-gnatls --RTS=ravenscar-sfp-stm32f4) but
gprbuild --target=arm-eabi can't.

Instead, you have to put the RTS in

   lib/gcc/arm-eabi/4.7.4/rts-ravenscar-sfp-stm32f4

when both are happy.
