[PATCH v2] resolv: Remove bogus targets that build ga_test

[hawkinsw at borlaugic dot com]

Per Mr. O'Donell's suggestion/feedback, I am sending a v2 of this very
simple patch that will remove the resolv/ga_test target and also remove the
resolv/ga_test.c source file. 

Again, I am trying to follow all the rules for the proper formatting
of patches and I hope that I did it correctly. Please let me know if
I did not. 

Thanks again for all the work that everyone does for the community!

--- commit msg:
Remove the bogus targets (and source) that supposedly build ga_test.
This code was added to resolv very early in the development process
but does not appear to be an actual test program. The target for
building this file is tests but because the glibc Make system is
built the way it is, the target is overriden by higher-level tests
targets and, therefore, the ga_test program is never built. Removing
the target and the source code makes the resolv/Makefile less confusing.

Tested by building and running 'make check' on 64 bit host running 
Kernel 4.10.0-19 configured with
 --prefix=/home/hawkinsw/code/glibc-build/install
 --enable-hardcoded-path-in-tests
 --disable-mathvec

	* resolv/Makefile: Remove bogus targets that build resolv/ga_test
	and resolv/ga_test.c itself.
