Version string added to gdbserver

[Girish Shilamkar <girish at linsyssoft dot com>]

Hi,
	gdbserver Makefile consists of following line:

# Perhaps should come from parent Makefile
VERSION = gdbserver-4.12.3

	In order to know which gdbserver is being run, the following patch
prints gdbserver version when gdbserver is started. 
	Should the gdb version also be displayed, from which gdbserver was
built (i.e gdb 6.4 etc), since gdbserver built from different gdb
versions may be different even if gdbserver version is same?

-Girish.
