Serialize install process to avoid multiple make depend operations

If make install is run with a large -j value (make install -j N , where
N < 1)

We can run into a situation in which the install fails because multiple
make depend operations are running in parallel, which will fail due to
makefile rewriting.

Serialize the install process to guarantee that those operations don't
step on one another

Fixes # 27074
