I guess I should qualify this comment a little.  I was talking about
linker operation, not what might happen in practice when you use
"-static -pie".  In practice, the archive libraries for -lc and so on
probably won't be compiled as PIC, and other toolchain and library
packaging issues may well prevent this working.  My point is the
linker itself should be able to support "-static -pie".
