It's still there, but it makes sense to move it to sage-check-64.

Okay, we can do these.

`SAGE64` will work on 32-bit hosts).

If SAGE64 is set to "yes", then the compiler flag "-m64" is added by
certain spkgs with no check on the platform. Is it the case this flag has
no effect except on OS X and Solaris?
> The name of the variable (and the "flag" file) is odd anyway (it should
IMHO be `SAGE_FORCE_64BIT_BUILD`), and there's [currently] no (analogous)
way to force a 32-bit build on systems that default to 64-bit...
I don't think we can change the name of the variable, but the flag file
could be renamed, since it's only used in sage-check-64. Any suggestions?
