Maven (1.x) build problems with custom ${maven.build.dir}

I've modified the maven.build.dir property in my build.properties file
as I prefer to put the build files in .target as opposed to target . I
encountered a problem when doing a full sakai build as a few maven.xml
scripts had the target directory hard coded into them so part of the
build was being placed in each directory and a proper war was not
being created.

Attached is a patch that fixes it for me. It is on Sakai 2.3.x
revision 21424 and from sakai root run `patch -Np0 < patchfile`.
