Issue

Looks like the recent gcc 7.5.0 builds somehow got GLIBC_2.14 symbols in them which breaks using them in cos6 environments:

(dev) keith@Keith-PC:~/scratch$ objdump -T bin/x86_64-conda-linux-gnu-c++ | grep GLIBC_2.14
0000000000000000      DF *UND*  0000000000000000  GLIBC_2.14  memcpy
(dev) keith@Keith-PC:~/scratch$ objdump -T bin/x86_64-conda-linux-gnu-cc | grep GLIBC_2.14
0000000000000000      DF *UND*  0000000000000000  GLIBC_2.14  memcpy
