[PATCH] print format does not match argument type

["Patrick Monnerat" <Patrick.Monnerat@datasphere.ch>]

In gdb/gdbtk/generic/gdbtk-register.c, 2 statements try to use a print
format of "%lx" for a size_t argument. The correctness of such
statements is architecture dependent. If warnings are treated as errors,
the compilation fails.
 
The attached patch fixes these statements by unconditionally converting
the size_t argument to an unsigned long.
 
Cheers,
Patrick
