body: <p>While build Go program with use of Cgo I get error</p>
  
  <pre><code>/usr/lib/go/pkg/tool/linux_amd64/link: running gcc failed: exit status 1
  /usr/bin/ld: /tmp/go-link-373355991/000002.o: unrecognized relocation (0x2a) in section `.text'
  /usr/bin/ld: final link failed: Bad value
  collect2: error: ld returned 1 exit status
  </code></pre>
  
  <p>Tried to google that issue and found some bugs (<a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=808205" rel="noreferrer">https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=808205</a>) on Debian and Ubuntu with C compiler and linker in versions of libc6 (2.21) which are newer than version I use (2.19). </p>
  
  <p>Also there mentioned having problems compiling C programs and I compile example in C successfully. </p>
  
  <p>I tried to build my Go program on other machine with same system and libraries versions and the build succeeded.</p>
