How can I always cross compile even when host and build are the same?

[Steven Stewart-Gallus]

Hello,

I would prefer to never invoke runtime tests such as for whether vfork is
effective and simply always cross compile even if host and build are the same (I
want people cross compiling from some other architecture to obtain the exact
same binary identical build as for my native builds.) How can I do this?

Thank you,
