[Qemu-devel] [PULL 7/7] allow to build with older sed

["Daniel P. Berrangé" <berrange@redhat.com>]

From: Jan Beulich <JBeulich@suse.com>

sed's -E option may not be supported by older distros. As there's no
point using sed here at all, use just shell mechanisms to establish the
variable values, starting from the stem instead of the full target.
