[uClinux-dev] for JEENI users

When debugging remote arm targets using  devices such as JEENI  from epitools 
the semihosting function slows execution by the target of SWI instruction 
nearly 100-fold.  This is especially annoying when you try to debug  linux 
kernel on the target as it uses SWI to implement system calls.  
The attached patch adds a set rdisemihosting {on/off/1/0/true/false} command 
to the gdb which allows one to enable or disable semihosting suppport.
the command shoud be executed before target rdi ....  command
The patch is against gdb 5.3 but i think will apply to older versions cleanly
