But “only” on Solaris (and I even question _that_ decision). In
particular,

 CC="gcc -m32" ./config.guess   # from sparc64, ppc64(non-IBM)
 CC="gcc -mx32" ./config.guess  # from x86_64

run from an sparc64-linux does not produce sparc-linux respectively,
nor should it.

The platform in both -m cases is sparc64, it is just that one chose
to use ELF32 objects (be it for performance reasons or just general
enjoyment). The situation is (loosely) like choosing between "small"
and "large" memory models in Borland Turbo C (and probably other
DOS-era compilers).
