clang/clang++ read from /etc/env.d/gcc to get the target flags/profile, it's up to the OS to maintain them and make sure they're correct, looks like that didn't happen for this OS.

My Gentoo ARM SBC based on an even more ancient armv4 arch has been chugging along just fine with the latest gcc/clang updates:

    grep CTARGET /etc/env.d/gcc -r
    /etc/env.d/gcc/armv4tl-softfloat-linux-gnueabi-11.3.0:CTARGET="armv4tl-softfloat-linux-gnueabi"

/etc/env.d is a Gentoo-specific directory to define default env vars for user sessions. It's not a feature of clang to read that directory, so it's not correct to assume other distros would have it. It's just that Gentoo's compiler setup reads the CTARGET env var to select the target, and Gentoo uses /etc/env.d to set it.

Is that why other distros break? :)

Gentoo always works .. it just takes longer :)
