Board configuration for ld tests

There are already some tool specific options in the config files, eg 
gcc,stack_size  and  gdb.nosignals  so maybe a linker specific option 
would be better.  Eg:

   ld,pre_flags	[Flags to appear on linker command line
                  before the test adds any flags]

   ld,post_flags [Flags to appear after any test specific flags]

Cheers
