gnu-ld: looping in map_segments

[John Breitenbach]

I guess I answered my own question.  Adding -lgcc_s to the linker's 
command line solves the problem.  I tried building with both 
binutils-2.18 and last week's snapshot.  Both complained about not being 
able to find libstdc++.  When I located this library in the compiler's 
path and added that directory to the linker's command line, I got errors 
regarding Unwind stuff.  Adding -lgcc_s solved that.  Both of the newer 
linker worked with these changes.  And when I went back to the linker I 
had been using, it works now, too.

This problem comes and goes with a trivial code change to one of my C 
modules - so I'm guessing its due to actual code size.  I add or remove 
one extra call to a function (4 instructions) which is already called 
many times, to see this problem come and go.
