1690937 - Build local-toolchains with a sysroot

Status: RESOLVED FIXED

(Firefox Build System :: Toolchains, task)

Description

[Mike Hommey [:glandium]]

There are two main kinds of toolchain tasks: those used internally on CI, and those used by bootstrap (local-toolchains). For the former, we don't really care that they're compatible with the largest number of systems. For the latter, it's kind of like Firefox, we want them to run on as many systems it's reasonable to support. So similarly to what we're going to do with Firefox, we'll build the local-toolchains with a sysroot, while upgrading the system version they're built from, without affecting their runtime compatibility.

We can't use the system compiler (gcc) because of
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=786883
(which despite being closed, still is a problem)
We could use the linux64-gcc toolchain, but since we're using clang
on other platforms, we might as well do the same.

For the same reason we used clang for sccache, we use clang here.

Similarly to sccache, we need to use clang.
