g77 pic case vs. binutils & readelf

[Robert Lipe]

I haven't tracked down where things are going wrong but this is an
interesting clue I wanted to throw out before I left this problem for 
a little while.

Sometime in mid-april several of the -fPIC g77 testcases started
aborting on OpenServer.  Last night, I found that it was the dynamic
linker that was dropping core. [ Details in that message. ] I just
fed one of the offending binaries to 'readelf -a' from the binutils
snapshots.  Since binutils is dropping core when reading the binary, I
assume the binary (for whatever reason) is malformed.

I'll try to dig more into it this weekend.
