Ah, it's a dash vs. bash thing. Either we need to change all bashisms
in the makefiles, or, since kvm-unit-tests already depends on bash for
its scripts, then we might as well just tell make to use it too. This
patch will fix it
diff --git a/Makefile b/Makefile
index 0d5933474cd8c..3e60b4f8e4a57 100644
--- a/Makefile
+++ b/Makefile
@@ -1,4 +1,6 @@
+SHELL := /bin/bash
+
ifeq ($(wildcard config.mak),)
$(error run ./configure first. See ./configure -h)
endif
I'll probably submit the patch in a second.
Thanks for hunting down the problem!
