RFE: java -L

[Jonathan Gibbons]

In the world of bootstrapping, it is common to use tools like javac, 
etc, and to override the location of the classes executed by those 
tools.  This is typically done by passing -Xbootclasspath to the 
underlying runtime, by prefixing it with -J, as in

     javac -J-Xbootclasspath:value ...

In our brave new world, there is no -Xbootclasspath; we get to use -L 
instead.   But it sure is ugly to have to prefix both the option name 
and value with -J, and write

     javac -J-L -Jvalue

Can we please change the options so that either -L can optionally take a 
value after a ':'  (i.e. "-L value" or "-L:value") or we have a new 
option like -XL which always takes the value after a ':' ?

I'm looking at all the work we need to do in the build to allow us to 
build javac so that it is executed in module mode, and simplifying the 
-L option would make it a bunchy easier.
