It takes care of the warnings, but I still see this:
Configuring for VCMA9 board...

This is with USE_PRIVATE_LIBGCC=yes and "gcc version 4.6.2 (Gentoo 4.6.2
p1.0, pie-0.4.5)" from Mike Frysinger's toolchain set.
Turning off USE_PRIVATE_LIBGCC produces more errors (lots of hard/soft
FP
conflicts, undefined "raise", and the same linker segfault).
Is this toolchain expected to work?
