arm build failure on gcc head

[Joel Sherrill]

Hi,

This looks like an issue with the gcc head (4.7.0)
Compiling the RTEMS head.  It looks like an extra
flag needs to be passed to ld and we are missing
something.

With the gcc head, you get this for the csb336 BSP.

arm-rtems4.11-gcc -mstructure-size-boundary=8 -mcpu=arm920 -mfpu=vfp 
-mfloat-abi=soft -O2 -g   m.c
/users/joel/test-gcc/install-svn/lib/gcc/arm-rtems4.11/4.7.0/../../../../arm-rtems4.11/bin/ld: 
error: /tmp/ccs3cuW7.o uses VFP instructions, whereas a.out does not

Any ideas?
