[MPlayer-dev-eng] Remove make warning

[Georgi Petrov]

Hi,

There is a warning before compiling each file in the tree:

makefile:949: warning: overriding commands for target `TAGS'
makefile:946: warning: ignoring old commands for target `TAGS'

The corresponding lines in Makefile are:

TAGS:
	rm -f $@; ( find -name '*.[chS]' -o -name '*.asm' -print ) | xargs etags -a

tags:
	rm -f $@; ( find -name '*.[chS]' -o -name '*.asm' -print ) | xargs ctags -a

They seem the same for me and since I don't really understand very
well the structure of a Makefile, can't we just remove the second line
(lowercase tags)?
