[Bug target/41939] New: EABI violation in accessing values below the stack.

4.4.x has a problem with the floating point emulation libraries with respect to
the EABI in that they access an area below the stack pointer.

This is fixed on trunk with
http://gcc.gnu.org/ml/gcc-patches/2009-06/msg00372.html but needs backporting
to 4.4.x and 4.3.x branches. I will do so once I've backported and regression
tested these.

cheers
Ramana
