    readelf: avoid shadowing a libiberty symbol
    
    With my (oldish) gcc I'm seeing
    
    .../binutils/readelf.c: In function ‘dump_ctf_indent_lines’:
    .../binutils/readelf.c:13851: error: declaration of ‘spaces’ shadows a global declaration
    .../binutils/../include/libiberty.h:253: error: shadowed declaration is here
