title: undefined reference to `__strtof128_nan@GLIBC_PRIVATE'
body: <p>I am trying to cross-compiling a packing to debian-8 (jessie), which comes with glibc-2.19. While cross-compiling the package it throwed the following error.</p>
  
  <pre><code>CMake Error at /usr/share/cmake-3.10/Modules/CMakeTestCXXCompiler.cmake:45 (message):
    The C++ compiler
  
      "/opt/jessiesdk-cxx/bin/i686-pc-linux-gnu-g++"
  
    is not able to compile a simple test program.
  
    It fails with the following output:

  <p>After a bit of googling i found <a href="https://abi-laboratory.pro/index.php?view=navigator&amp;symbol=__strtof128_nan%40%40GLIBC_PRIVATE#result" rel="nofollow noreferrer">ABI Laboratory</a>. Does this mean i require a glibc at least 2.26 in order to compile the package ?</p>
  
  <p>Is there a way around this ?</p>
  
  <p>Thanks..</p>
