RFC: Static linking option.

[David Daney]

I have been thinking about adding an option to gcj to cause it to link 
against a static libgcj.  Probably something like '-static-libgcj' and
'-shared-libgcj' similar to the libgcc options of similar names.

There are two ways to do it that I have thought of:

1) Wrap -lgcj with -non_shared and -call_shared when generating the 
linker command line.  No library rename necessary, but may only work 
with GNU binutils.

2) Rename libgcj.a to libgcj_static.a.  Then pass -lgcj_static to the 
linker.  Probably more portable, but requires changing the build process 
to generate the static library with a different name.

Thoughts?
