A bit below the check for --gc-sections, GLIBCXX_CHECK_LINKER_FEATURES actually
checks for another linker feature in a way that doesn't break crosscompiling:

    cxx_z_relo=`$LD -v --help 2>/dev/null | grep "z relro"`
    if test -n "$cxx_z_relo"; then
      OPT_LDFLAGS="-Wl,-z,relro"
      ac_ld_relro=yes
    fi
    AC_MSG_RESULT($ac_ld_relro)


The same trick will work for gc-sections as well.
