    [gdb/testsuite] Fix gdb.base/nested-subp{2,3}.exp with recent ld
    
    On openSUSE Tumbleweed (with ld 2.39) I get for test-case
    gdb.base/nested-subp2.exp:
    ...
    gdb compile failed, ld: warning: tmp.o: requires executable stack \
      (because the .note.GNU-stack section is executable)
    ...
    
    Fix this by compiling with -Wl,--no-warn-execstack.
    
    Likewise in gdb.base/nested-subp3.exp
    
    Tested on x86_64-linux.
