+	  XML-RPC is a quick-and-easy way to make procedure calls over
+	  the Internet. It converts the procedure call into an XML
+	  document, sends it to a remote server using HTTP, and gets
+	  back the response as XML.

+Fix build of host tool
+
+genmtab is a tool that needs to be built for the host as it is used
+during the compilation process of libxmlrpc. Its Makefile needs a bit
+of tuning to use the conventional CC_FOR_BUILD, CFLAGS_FOR_BUILD and
+LDFLAGS_FOR_BUILD variables.

+Use correct curl-config program

+Instead of calling again curl-config in src/Makefile (which ends up
+calling the wrong curl-config: the one in the PATH instead of the one
