[PATCH RFC v1] Dockerfile: Have "sandbox" build with i386 toolchain not x86_64 toolchain
A long time ago, we had to use "i386" and "x86_64" toolchains for our x86 platforms, depending on the target. We then moved to being able to use the single "i386" toolchain to support all x86 platforms. At the same time, we had been building sandbox with our "x86_64" toolchain in CI. When x86 switched to being able to use a single toolchain we did not update our CI buildman file to match. Do this now as we want to ensure that sandbox is built with the same compiler version the rest of our platforms are and not the host one.

I'm posting this as an RFC to start the discussion as when I mentioned this to Simon on IRC, he was very much not in agreement.
My main argument is this, sandbox needs to use the same toolchain that we compile (virtually) all other platforms with as one of the points is to be able to catch warnings and compiler behavior changes as soon as possible in our CI. And just like how developers can use distribution-provided toolchains today, nothing changes in that regard, we only make CI be more consistent now. --- tools/docker/Dockerfile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)

OK, that makes some sense to me, actually. It isn't the toolchain that people will be using, but catching things earlier seems good.
The main concern I have is that we are not testing sandbox on the toolchain that everyone will be using. But I haven't noticed failures in CI which I cannot repeat locally, so we can cross that bridge when we come to it.

This doesn't seem to work, for a few reasons:
1. Buildman doesn't support setting HOSTCC and CC unless using -O to override the toolchain (so the setting in this patch has no effect) 2. Using the toolchains from kernel.org gives this error:
NO_LTO=1 make O=/tmp/b/sandbox defconfig all HOSTCC=/home/sglass/.buildman-toolchains/gcc-13.2.0-nolibc/x86_64-linux/bin/x86_64-linux-x86_64-linux-gcc CC=/home/sglass/.buildman-toolchains/gcc-13.2.0-nolibc/x86_64-linux/bin/x86_64-linux-x86_64-linux-gcc -j30 -s /home/sglass/.buildman-toolchains/gcc-13.2.0-nolibc/x86_64-linux/bin/../lib/gcc/x86_64-linux/13.2.0/../../../../x86_64-linux/bin/ld: cannot find crt1.o: No such file or directory /home/sglass/.buildman-toolchains/gcc-13.2.0-nolibc/x86_64-linux/bin/../lib/gcc/x86_64-linux/13.2.0/../../../../x86_64-linux/bin/ld: cannot find crti.o: No such file or directory /home/sglass/.buildman-toolchains/gcc-13.2.0-nolibc/x86_64-linux/bin/../lib/gcc/x86_64-linux/13.2.0/../../../../x86_64-linux/bin/ld: cannot find -lc: No such file or directory /home/sglass/.buildman-toolchains/gcc-13.2.0-nolibc/x86_64-linux/bin/../lib/gcc/x86_64-linux/13.2.0/../../../../x86_64-linux/bin/ld: cannot find crtn.o: No such file or directory collect2: error: ld returned 1 exit status make[3]: *** [scripts/Makefile.host:95: scripts/basic/fixdep] Error 1 make[2]: *** [/scratch/sglass/cosarm/src/third_party/u-boot/files/Makefile:503: scripts_basic] Error 2 make[1]: *** [/scratch/sglass/cosarm/src/third_party/u-boot/files/Makefile:568: __build_one_by_one] Error 2 make: *** [Makefile:177: sub-make] Error 2

That shouldn't matter tho.

So yeah, here's the real problem. In the past the kernel.org toolchain was (unintentionally I believe) good enough to make user-space programs too. That's not the case now, and sandbox is really a userspace program and not a bare-metal program.
So really the current line from the Dockerfile just needs to be removed.
