The KConfig infrastructure hardwires the compiler name to gcc, which
breaks
the BUILD_CC feature. This is needed even when cross compiling because
make *config rely on the kconfig infrastructure

Can you elaborate ? I'm not aware of any issues with either the host
builds or
target builds with the kernel.

Aha. I found the 0/N for the series.

And my answer is still the same. These belong upstream, and since the
kernel is fairly
picky about the compiler and compiler versions, I don't see a pressing need
to carry
something like this until it makes it into the mainline kernel.

My answer to 'can't assume the name of gcc', is to make sure that your
environment
and path is fully understood, and make your compiler available as 'gcc',
versus trying
to patch multiple recipes.

Cheers,

Bruce

If there's an issue, we need to fix it upstream .. not here.

We don't carry patches to linux-yocto like this, they are sent to the
linux-yocto mailing list, and
integrated into the tree itself.
