glibc: add task to list exported symbols

Browse Source 
When upgrading glibc it's important to know if there are any new symbols
that pseudo needs to wrap. In the future a generalised ABI comparison tool
would be good, but to solve the immediate need we can simply list the
exported symbols to files in WORKDIR.
