Gcc currently ignores -pie when there is a -shared due to treatment
of Scrt1.o.  However, this behavior is undocumted.  We like to
match the linker behavior with gcc.

Is this gcc behavior intentional? Will this gcc behavior ever
change? Can we document this gcc behavior?

BTW, this is another problem which can be handled like:
