[patch] string cosmetics for SUSV3_LEGACY

[Bernhard Fischer]

Hi,

The attached patch makes sure that we do not create empty object files
when SUSV3_LEGACY functions are turned off.

Ok?

Also, i'd like to know if it is a good idea to provide fallback defines
for the bcopy/bzero et al if SUSV3_LEGACY was explicitly turned off?
I certainly would have expected that these (impls and fallback defines)
are _not_ available at all when i turned the option to support them off.

thanks,
