[dmd-internals] Shouldn't there be a dmd switch to specify search paths for libraries?

dmd could add a library search path for optlink by adding it to the LIB 
environment variable. The work-around for Visual D is to manually modify 
sc.ini, appending %DMD_LIB% to the respective line and passing 
additional paths through that environment variable when building.

(BTW: LIB is a dangerous environment variable for optlink because it is 
widely used by other compilers, and libraries of unsupported formats can 
cause optlink to fail without reporting an error.)

If modifying optlink is such a hassle, it would be nice if dmd could 
modify the LIB environment variable from a command line switch.
