bazel_bootlin's Issues

MAC OS support

Hello,
Thanks for this great repo!

In any case, do you have any plan to support mac os with Apple silicon chip?
Also, I am wondering if I can build a target for linux machine deployment on Mac OS host.

Thanks in advance.

aarch64 doesn't use hermetic toolchain

I did a fresh checkout of the repo and on aarch64 It looks like /usr/bin/gcc is used instead of the gcc wrapper.

It's using the gcc from toolchain but for some reason it doesn't find these headers. I might have closed out this too soon: #5

execvp fails for x86-64-linux-gnu-2022.08-1

Hi, I'm trying to setup this toolchain and for some reason it works for aarch64 but not x86-64:
