This issue was found on system which had libstdc++ dynamic library not functional.
It is pointing to broken link which results in error:

/usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/4.4.5/libstdc++.a(ios_init.o): relocation R_X86_64_32 against `pthread_cancel' can not be used when making a shared object; recompile with -fPIC

Each time dynamic library tries to use stdc++, as libstdc++.so was broken link.

Currently SlapOS requires "sane" host: which has working libc, libc++ and gcc.

Some day in future SlapOS node software can provide own compiler, toolchain
and libc with libc++.

This reverts commit 6819f5a8.
