libgcc/ChangeLog:
* libgcov-driver.c (merge_summary): Remove function as its name
is misleading and doing something different.

The patch fixes tree-prof.exp tests on solaris11 and i686-linux-gnu,
problem was that sizeof of a pointer is different from sizeof gcov_type.
I'm going to install it if there are no objections.
Thanks,
Martin
