-L switch

[Jonathan Gibbons]

Various JDK tools are now beginning to accept a "-L library" option. 
(java, jmod, javac etc)

It would help if the java command's "-L library" had a variant that did 
not involve whitespace. The reasons are the same as for the java 
command's "-bootclasspath path" and "-Xbootclasspath:path" options. If 
you have a tool that is invoked by the launcher, it is helpful to be 
able to tunnel options to the JVM using the -J convention.     e.g.    
javac -J-Xbootclasspath:my-path.

With the current spec of the -L option, we will have to cross our 
fingers and hope that it works to prefix both the option and the 
argument with -J, as in
      javac -J-L -Jmy-library

I have two suggestions on how we can achieve this:

1.    Allow "-L:my-library" as well as "-L library"
2.    By analogy with -bootclasspath, provide "-XL:path"
