Subject: glibc: fix parallel build issue with make-4.4

We only need a one-line change in upstream fix (because we don't use
"make --shuffle").  Add it as a sed for both Chapter 5 and Chapter 8.

Note that the "minimal" sed would be '/MAEKFLAGS :=/s/r/ -r/'.  I
included an additional ')' so it won't modify "-r" again to "- -r".

Tested "make" and "make check" on a x86_64 with -j8 and an arm64 with
-j24.
