I believe that this has been the case for some two years or longer.

I found two references to junction=roundabout in the source code:

src/uk/me/parabola/mkgmap/reader/osm/HighwayHooks.java
src/uk/me/parabola/mkgmap/osmstyle/StyledConverter.java

In HighwayHooks, you might want to remove this code:

			// if the way is a roundabout but isn't already
			// flagged as "oneway", flag it here
			if ("roundabout".equals(way.getTag("junction"))) {
				if (way.getTag("oneway") == null) {
					way.addTag("oneway", "yes");
				}

Another method would be to add oneway=no to the junction=roundabout 
ways.

Best regards,
