The gcj compiler needs to pass -no_pie for linkage on darwin11 due

passing -no_pie on SYSTEMSPEC

I included it in the
triplet match to simplify the syntax. Bootstrap and tested on x86_64-
apple-darwin11.
Okay for gcc trunk?

* libjava/configure.ac (SYSTEMSPEC): Pass -no_pie for darwin11.
* libjava/configure: Regenerate.
I would like to see some more analysis of what the underlying reasons
for failure are.
-fpie works fine with darwin 9 and darwin 10 libjava [XCode 3.1.4 and
3.2.5 respectively, bootstrap w/4.2.1]
(modulo suppressing it when building test-suite .dylibs *** - which
is a testsuite options handling issue - not a fundamental problem).
so:
make -k check-target-libjava "RUNTESTFLAGS=--target_board=unix/-fpie\{-
m32,-m64\} "
passes without regression (re the no pie case) given that pie is
suppressed for dylibs.

So is your proposed patch a work-around for (as yet unreleased)
darwin 11 tool-chain bugs or ... ?

kludge to suppress pie for for dylibs (use in place of the darwin9.h
hunk from the attachment on PR49371).
