What are the use cases for the cross-compilers?
If these are to compliment the Fedora secondary archs, then compiling
kernels is probably the main use of cross-compilers
I've talked to a number of kernel developers, all of whom would like this.
Once you're up on the device, you can build there, or you can use
It's a principle of secondary archs that packages are built natively,
either on hardware or in emulation.
Even NOMMU arches can build their own packages, provided they don't require
too much in the way of RAM.
On the other hand, if you're trying to cross-compile userspace,
whole different thing -- a lot more work, and perhaps much less needed.
And much more prone to multiplication.
Take MIPS, for example. We only need one cross-compiler to build MIPS kernels,
since you can switch the compiler between variants of BE/LE, 32/64 and
suchlike. Take FRV as another example: you only need the one compiler to build
both MMU and NOMMU kernels.
However, each combination of variants (eg: MIPS-32BE) requires a separate
userspace libraries, headers, etc.
