This patch is taken from:

When we re-exec the master makefile in a jobserver environment, ensure

that MAKEFLAGS is set properly so the re-exec'd make runs in parallel.

See Savannah bug #33873.

bug #33873: MAKEFLAGS=-jN gets lost on reexec

sr #107487: MAKEFLAGS not being honored always (regression) in 3.82
