After bumping the GCC version to 6.2.0 due to #13893 building GCC 6.2.0 is busted for 64bits in our gitian setup:

/usr/bin/ld.bfd.real: gcov.o: relocation R_X86_64_32 against `.rodata' can not be used when making a shared object; recompile with -fPIC

This works fine with hardening-wrapper settings as we have them in Gitian on a Debian testing machine. Additionally, setting DEB_BUILD_HARDENING_PIE=0 for the GCC step in our Gitian build would help as well.

The Wheezy compiler is too old for it (generally 4.x).

Okay, I bisected the problem (PIE enforcement breaks the compiler) and pushed a fix for review to bug_20301 ( in my public repo.

Taking off the review queue as GCC 6 seems to be too unstable to use right now. See #20381 for further details.
