look for the last dot in the filename, not the first one

When the filename for the ".d" file is chosen automatically (i.e. not specified
on the command line), the basename is computed from the input file(s) by
removing everything after the *first* dot and adding a ".d" extension.

So, given an input file foo.bar.cpp, it will choose foo.d

GNU GCC would have chosen foo.bar.d because it computes the basename by looking
for the *last* dot.

The patch attached makes clang act like gcc.
