Subject: tests/functional/s390x: Add reverse debugging test for s390x
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f397b7652dac77bf24a491dfee8def59a5d2591f;p=thirdparty%2Fqemu.git

tests/functional/s390x: Add reverse debugging test for s390x

We just have to make sure that we can set the endianness to big endian,
then we can also run this test on s390x.
