Filed as gcc bug 40411.  I can repost when I hear back.

While waiting for gcc to fix this, users can work around 
by doing --extra-libs=/usr/lib/{32 or 64}/values-xpg6.o

(using Sun compiler is not an option without some work -- it does not 
successfully compile ffmpeg)

Agree the execution check is not suitable for cross compilation.

The patch might not be ideal for the cross environment, but the outcome is 
no worse than current (and improved significantly for native).  Use in 
cross environment could be improved by using --sysroot argument in the 
paths (I'll repost a modified patch if necessary after gcc bug is 
evaluated).
