Subject: ci: cross-build Linux aarch64 binary
X-Git-Tag: 0.4.0~17^2
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=ffc7444fa6b0c933a3cdee30db5dab0237a9021f;p=xen-guest-agent.git

ci: cross-build Linux aarch64 binary

Testbuilding only, as we don't have an obvious use-case to support.

Builds against glibc in a Debian chroot to be able to check
the xenstore build feature.
