Do we even support not using --cross-prefix ? I'd have expected just setting CC to run into random problems like using the host arch's version of strip rather than the cross toolchain, the host's pkg-config rather than the one that knows where the cross libraries are, etc etc. >> Instead, test whether host compiler is same as target compiler, >> which also works when --cross-prefix is used. > > I'd much rather remove this test altogether.

I think looking at the host CPUs we support the only ones that aren't guaranteed either big or little endian are (a) mips and (b) ARM. ARM already identifies big-endian by a compile-time check, and it seems likely that MIPS could too. -- PMM
