    Testsuite: Make it easier to debug environment setting functions
    
    This adds verbose output to dg-set-compiler-env-var and dg-set-target-env-var
    so you can actually see what they're setting when you add -v -v.
    
    gcc/testsuite/ChangeLog:
    
            * lib/gcc-dg.exp (dg-set-compiler-env-var, dg-set-target-env-var): Add
            verbose output.
    
    (cherry picked from commit e410cbff5d5a408b7c64a0c426951afc2a24df93)
