Almost right.  To cope with *both* the middle and the right column,
parallel make is forbidden.  So it'll work only with GCC.  Or you
could work in a temporary directory.

Your patch also forbids parallel 'make install' with GCC in case objects
with the same names as the one you remove are created as part of the
regular build, and in case the objects are created in the build tree,
which I still don't know.
