[Qemu-devel] [PATCH] Makefile: Don't find and delete when $(DSOSUF) is e

Subject: [Qemu-devel] [PATCH] Makefile: Don't find and delete when $(DSOSUF) is empty in "make clean"

DANGEROUS: don't try it before you read to the end.

A first "make distclean" will unset $(DSOSUF), a following "make
distclean" or "make clean" will find all the files and delete it.

Including all the files in the .git directory!

Fix it by only do it when $(DSOSUF) is not empty.
