Yeah, we had the same problem and had to write the <tag> rule to prevent 
appending "lib"

rule tagrule ( .name : type ? : property-set )
{
    #ECHO $(.name) $(type) ;
    local ret = "" ;
    if ( $(.name) = $(name) & $(type) = SHARED_LIB )
    {
        # return itga.so, get extention for SHARED_LIB
        local ext = [ type.generated-target-suffix $(type) : $(property-set) ] ;
        ret = $(name:S=.$(ext)) ;
    }
    return $(ret) ;
}
