    [testsuite] Pass pthreads in prepare_for_testing
    
    "pthreads" in the right flag to pass in prepare_for_testing to linker,
    instead of additional_flags.  Without this patch, the test case can't be
    complied by clang.
    
    gdb compile failed, clang: warning: -lpthread: 'linker' input unused
    
    gdb/testsuite:

    	* gdb.base/info-os.exp: Pass pthreads.
    	* gdb.multi/multi-attach.exp: Likewise.
