Actually these targets exist in the gcc subdirectory.
Which is mentioned slightly above:
```
In order to run sets of tests selectively, there are targets
@samp{make check-gcc} and language specific @samp{make check-c},
@samp{make check-c++}, @samp{make check-d} @samp{make check-fortran},
@samp{make check-ada}, @samp{make check-m2}, @samp{make check-objc},
@samp{make check-obj-c++}, @samp{make check-lto} in the @file{gcc}
subdirectory of the object directory.
```
Though maybe it should be clear that these make targets are talking
about the targets in the gcc subdirectory rather than from the
toplevel.
