you have not answered these questions:
a) "what is anything being built in these tests which is not PIC"?
b) and why is it being built that way?
ISTM the fix below should not be required
- and the problem lies in something being built with -mdynamic-no-pic
or similar
- that is what we should fix.

on x86_64-apple-darwin11 due to the -pie linker default. The
attached patch
uses -fno-pie on darwin to insure that -no_pie is passed to the
linker when
targeting darwin11 or later. This approach is used because istarget
doesn't
support complex regex to allow -Wl,-no_pie to be passed for darwin11
and later
only (since only recent Xcode releases understand the -no_pie linker
option).
Also, -fno_pie has the advantage of supporting -mmacosx-version-min
usage.
Regression tested on x86_64-apple-darwin11...

Okay for gcc trunk?
