Indeed, this is misleading. But I named the option as par with the others
around it:
    ARCH_SUPPORT_CPU    --> supports --with-cpu=    and  -mcpu=
    ARCH_SUPPORT_TUNE   --> supports --with-tune=   and  -mtune=
    ARCH_SUPPORT_FLOAT  --> supports --with-float=  and  -mfloat=
    ARCH_SUPPORT_FPU    --> supports --with-fpu=    and  -mfpu=

Of course, this does not match for the following option:
    ARCH_SUPPORT_SOFTFP

Also, the options are not consistenly named:
    ARCH_SUPPORT_CPU  but  ARCH_SUPPORTS_64

This could probably be improved, indeed... I'll see if I can get sometime
for it soonish...

Thanks for the review!

Regards,
Yann E. MORIN.
