[kvm-unit-tests PATCH 4/4] Test compilation with Clang on aarch64, ppc64le and s390x in Travis-CI

[Thomas Huth <thuth@redhat.com>]

Travis-CI recently changed their policy so that builds on the non-x86
build machines are possible without consuming any credits again. We can
use these systems to test compilation of the non-x86 code with Clang.
Unfortunately, the qemu-system-s390x of Ubuntu 20.04 seems to be buggy,
so that the s390x binaries cause that QEMU to crash. Thus we can only
run the TCG tests for ppc64le and aarch64.
