There's a simple workaround for most cases, condition asm-thunks on
!flag_write_lto.  We'll do this if a proper implementation doesn't come up
for 4.5.

Another testcase in PR41602.  SPEC CPU 2006 450.soplex is the only one in
SPEC 2000/2006 to run into this issue.

Initial fix at http://gcc.gnu.org/ml/gcc-patches/2008-12/msg00953.html
Keeping open as thunks with varargs are still broken.

This case can be easily fixed by setting targetm.asm_out.can_output_mi_thunk to
NULL. This will introduce a performance regression.

The only case that will be missing is varg functions.

The llvm equivalent bug is http://llvm.org/bugs/show_bug.cgi?id=2861.

To reproduce:
g++ -O2 -c thunk.C -flto-single -o thunk-lto.o
g++ -O2 -c thunk.C -o thunk.o

readelf -s thunk.o  | grep Th
35:  6 FUNCWEAK   DEFAULT   19 _ZThn8_N1C1fEv
readelf -s thunk-lto.o  | grep Th
26:  0 NOTYPE  GLOBAL DEFAULT  UND _ZThn8_N1C1fEv
