[binutils-gdb] Skip linker tests for unique symbols in shared libraries if the target does not support building sha


https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=319b82e47dd12d6554e17a2ceedd3139b88ba55f

commit 319b82e47dd12d6554e17a2ceedd3139b88ba55f
Author: Dimitar Dimitrov <dimitar@dinux.eu>
Date:   Wed Jan 18 12:23:19 2017 +0000

    Skip linker tests for unique symbols in shared libraries if the target does not support building shared libraries.
    
    ld	* testsuite/ld-unique/unique.exp: Filter shared lib cases in
    	uniqeue.exp, as not all targets have such support.
