Here's where it explodes:
into Source/cmSystemTools.cxx, starting from line 2378:
//----------------------------------------------------------------------------
bool cmSystemTools::GuessLibrarySOName(std::string const& fullPath,
std::string& soname)
{
// For ELF shared libraries use a real parser to get the correct
// soname.
#if defined(CMAKE_USE_ELF_PARSER)
cmELF elf(fullPath.c_str());
if(elf)
{
return elf.GetSOName(soname);
}
#endif
...
Probably something fishy in the arm toolchain.
The diff below disables elf parsing on arm:

What's the right way to disable USE_NINJA on arm?
cause ninja does not work without the ELF parser.
