[Qemu-devel] [PULL 04/11] configure: Only build the s390-ccw bios if the compiler supports -march=z900 |

From: Thomas Huth <address@hidden>
We want to build our s390-ccw bios with -march=z900 so that it also
works with the oldest s390x CPU that we support with TCG. However,
Clang on s390x does not support -march=z900 anymore, so we can not
use this compiler to build the s390-ccw bios. Thus add a proper test
to the configure script to see whether the compiler is usable.
