    app-admin/lnav: Backport to build with gcc-11
    
    This commit partially[0] backports a patch from upstream[1][2] to
    allow lnav to build with gcc-11.
    
    This patch was tested with gcc-10.2.0-r5 and gcc-11.1.0.
    
    [0] Only the changes to m4/ax_cxx_compile_stdcxx.m4 were necessary
        to address the gcc-11 fix.
