[meta-virtualization] [PATCH] openvswitch: Fix compile problems with i586-nlp

[Jason Wessel]

If you have in your $CC from the compiler template any kind of
directive which contains a comma character it is going to cause ovs to
not build due to the macro expansion in the Makefile:

CC = $(if $(C),env REAL_CC="'"$CC"'" CHECK="$(SPARSE) -I $(top_srcdir)/include/sparse $(SPARSEFLAGS) $(SPARSE_EXTRA_INCLUDES) " cgcc $(CGCCFLAGS),'"$CC"

Put more simply:

CC = $(if $(C), CONFIGURE_CC_DEFINITION, cgcc args CONFIGURE_CC_DEFINITION)

The CONFIGURE_CC_DEFINITION for the i585-nlp definition had
"-Wa,-momit-lock-prefix=yes".  The comma there caused a strings to
"break" in the wrong place in the $(if) macro and the build of recipe
will fail with the error shown below:

/bin/sh: -c: line 1: unexpected EOF while looking for matching `"'
/bin/sh: -c: line 3: syntax error: unexpected end of file

The solution is to transform the "-Wa," -> "-Xassembler ".
