Changing compilation options for BSP building

[john.pickwick at free.fr (John Pickwick)]

Hi to all,

What should I do to change the compilation options used during my bsp buid ?
I use the LEON2 / RTEMS 4.6.5 BSP and I'd like to replace the "CPU_FLAGS 
= -mcpu=cypress -msoft-float" option used during the compilation to suppress 
the soft-float setting.

I tried to set CC_FLAGS_TARGET or CPU_FLAGS directly on my configure command 
line but it does not work (failed with an 'invalid build alias' error).

Thanks for help,
John.
