At least on x86, there is/was a shlib size boundary beyond which you
needed to generate different instructions with wider offset fields
in order to have position-independent code.  Thus the difference
between -fpic and -fPIC.  It's at least possible that the OP's Go
toolchain automatically uses -fpic, but I'm suspicious of that theory.
Usually you don't use either switch when building .a libraries.
