This makes it build for all architectures e.g. riscv/mips/ppc etc.

Using clang-native to build all variants of recipe makes it easier to
handle compiling with various distros choosing different runtimes

I realize that this is a fairly old commit... anyway.

During the weekend I decided to update a personal project of mine to the
tip of master, but after performing the main required changes, I faced
compiler-rt build failures, complaining about unrecognized -mcpu
argument during the compiler sanity check in do_configure[1].
Bisecting oe-core points to this commit. The project I'm using uses
-mcpu=cortex-a72.cortex-a53+crc+crypto (DEFAULTTUNE =
"cortexa72-cortexa53-crypto"), which is not accepted after this change.

Is this a user error, and I'm supposed to change something after this
revision, or is this a regression?

Thanks

clang has differences in syntax for big.LITTLE arm systems sadly. In meta-clang
we have a fix for this
https://github.com/kraj/meta-clang/blob/master/classes/clang-legacy.bbclass#L25-L38

We need to do something similar in either clang bbclass or in recipes
using toolchain-clang
override.

Thanks a lot. Will run some tests in the coming days, and if I don't
find any issues locally, will try to submit a patch (I think it would
make sense to put it in clang.bbclass, most likely others would stumble
upon this too over time)
