  I've worked around this in the past by exporting "LIBS=-lc", but without

  this issue now.
  
  Firstly, "-lc" is passed to the linker without the previous workaround.

2017-05-12 Thread Chris Coulson 
Subscribing doko, as I'm not sure if there's a subtle glibc bug here
(with the ordering of libraries in the libc.so linker script).

I can only reproduce this on trusty's toolchain in any case, so not
particularly important. And only on x86 (the compiler doesn't appear to
emit calls to stack_chk_fail_local on x86-64).
