Subject: tests: lxc-test-reboot: Fix build on ia64
X-Git-Tag: v6.0.0~87^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=16c6ff22693a7c5419e4f36b4b8158d5dccbceec;p=thirdparty%2Flxc.git

tests: lxc-test-reboot: Fix build on ia64

Add the prototype for __clone2(...) that is used on ia64, and adjust the
code to use it via macro tests.

Verified that the code compiles properly on Debian's ia64 porterbox
(yttrium), but was unable to actually run as lxc-test-reboot requires
root privileges.
