unix: install libc6-dev:i386 in Clang build environment

indygreg · indygreg · commit e302f0e220cf · 2021-02-24T13:00:23.000-08:00
This is needed to get Compiler-RT to detect support for i386 so that
it builds the runtime libraries for that architecture. This should
hopefully enable us to PGO i386 builds.
