+    evmctl: use correct include for xattr.h
+
+    The xattr API/ABI is provided by both the c-library, as well as by the
+    libattr package. The c-library's header file is sys/xattr.h, whereas
+    libattr's header file can be found in attr/xattr.h.
+
+    Given none of the code here *links* against the libattr.so shared library, it
+    is wrong to *compile* against libattr's API (header file).
+
+    Doing so avoids confusion as to which xattr.h is used as the least problem,
+    and potential ABI differences as the worst problem due the mismatching header
+    file used.
+
+    So make sure we compile and link against the same thing, the c-library in
+    both cases.
