PATCH: Prevent mn10300 assembler from relaxing calls to weak symbols

[Nick Clifton]

Hi Guys,

   I am going to apply the attached patch which fixes a bug in the 
mn10300 assembler.  Prior to the patch the mn10300 assembler relaxation 
code would decide to relax a call to a defined, weak symbol.  This is a 
bad idea since of course the symbol can be overridden during linking, 
possibly invalidating the relaxation.

Cheers
   Nick
