What about using
https://github.com/ghaskins/schedtop/pull/1/commits/19d9d3d16e4731c97f1395ba2127fe48a46bb765
which does pretty much the same thing, but with additional fixes ?

Why do you need to customize OBJDIR ?

The LIBRARIES change would be taken care of if a patch like
https://github.com/ghaskins/schedtop/pull/1/commits/19d9d3d16e4731c97f1395ba2127fe48a46bb765
is used.

Are you sure += in shell as the expected result ?

Thanks!
