Why not simply ${TOOLCHAIN}?
That would be a big assumption that TOOLCHAIN is also the name of the binary,
which fails for any native builds.
But it would also work here…
OK. Let's rather not use anti-patterns whenever we can so people aren't
tempted to copy this for recipes that can be native/nativesdk too.
Please ignore my suggestion for TOOLCHAIN.
Have you checked we can build u-boot-tools, u-boot-tools-native and
nativesdk-u-boot-tools with clang?
FWIW, upstream CI exercises the build with clang so it should work. Our CI
will be doing build+boot tests of some clang builds with qemu.
From my shell history when I built Rockchip boards in U-Boot with clang
a few months ago I had run:
make CROSS_COMPILE="aarch64-linux-gnu-" O=build/puma HOSTCC=clang
CC=clang puma-rk3399_defconfig
So we need to check HOSTCC is proper and that we really need to add
${TARGET_PREFIX} in front of gcc/clang in CC.
I thought u-boot-tools includes u-boot.inc but it doesn't, so ignore my
previous comment (we should however verify at some point we can build
with either toolchain).
Cheers,
Quentin
