    [gdb/testsuite] Fix gdb.base/infoline-reloc-main-from-zero.exp with recent ld
    
    On openSUSE Tumbleweed (with ld 2.39) and test-case
    gdb.base/infoline-reloc-main-from-zero.exp, I get:
    ...
    gdb compile failed, ld: warning: infoline-reloc-main-from-zero has a LOAD \
      segment with RWX permissions
    UNTESTED: gdb.base/infoline-reloc-main-from-zero.exp: \
      infoline-reloc-main-from-zero.exp
    ...
    
    Fix this by compiling with -Wl,--no-warn-rwx-segments.
    
    Tested on x86_64-linux.
