fPIC issues: dies building binutils

[justincormack]

Trying to build from git head (on Ubuntu 12.04 x86_64) I get...

Doing export CFLAGS=-fPIC and adding -fPIC in the CFLAGS in bootstrap.sh seems to fix it so far, if anyone else having this issue.

Aargh! still getting the same problem, something not built with -fPIC. I hate libtool.

according to the README the authors intention was to build everything statically
so the real bug is not a lack of fpic, but that something wants to build shared stuff
