[pushed] testsuite, Objective-C: Fix duplicate libobjc cases.

[Iain Sandoe <iains.gcc@gmail.com>]

tested on i686, powerpc, x86_64 Darwin, x86_64, aarch64 Linux, pushed
to trunk, thanks,
Iain

Two of the encode testcases include '-lobjc' as their dg-options.
Since the library is already appended as part of the generic testsuite
handling,  this means that two instances appear on the link line leading
to spurious warnings from Darwin's new linker.

gcc/testsuite/ChangeLog:

	* obj-c++.dg/encode-10.mm: Remove unneeded '-lobjc' option addition.
	* obj-c++.dg/encode-9.mm: Likewise.
