It's not the CRC of libc.so you want, it's the CRC of the debug file.

So your libc.so apparently has a .gnu_debuglink section in it which says 
that there should be a debug image with a CRC of eadc3e5a.

The slightly odd thing is that your strace suggests it isn't finding a 
debug image, so I'm not sure why it is calcing the CRC of the main file 
instead.

None the less, if you have built with a separate debug file then you 
need to install it so valgrind can find it.
