When building a shared library, link it against libgcc_pic.a instead of the
non-PIC libgcc.a. Linking non-pic code into a shared library is not
a good thing. It happens to break amd64 at compile time, and the ppc
folks want it too. The problem is mainly with C++ code, unwind-dw2.c
in particular. Most of the other functions in libgcc.a are self
contained so most of the time it isn't a problem. The dwarf2 unwinder
is not safe though since it does make global variable references.
