Log Message:
Build PIC libs on MIPS and PPC64. While the normal calling convention is
position-independent, real PIC defaults to Global Dynamic as TLS model,
while non-PIC and PIE code can use more restrictive models like Initial
Exec. This is most visible with the thread_local destructor code now
using TLS in libc as it would be clobbered by any other shared library
with TLS due to static offset assignment by ld.
