Er, if you're building an arm-linux toolchain and store the sysroot in a 
noarch rpm, that's still wrong arch :-)  Not *as* wrong as having it in 
an RPM for the build host's arch, but not as right as having it for the 
target arch.

Eh?

If I understand you correctly, that sounds about right.  When cross 
building you need to pull in a mixture of native (host-arch) and cross 
(target arch) packages to meet the build dependencies.  This is part of 
where the "fun" is.
