Recursive Makefiles: avoid race condition in the install target

The `install` Makefile target of the top Makefile has `all` and
`install-recursive` as prerequisites. This leads to the two recursive
Makefile calls `make -C <SUBDIR> all` and `make -C <SUBDIR> install`.

The problem is these two targets try to build the same object files and
this leads to a race condition between these two targets in case of a
parallel build.

Fix this problem by removing the `all` prerequisite from the `install`
target, as it is not needed since all the `install` targets in the
sub-Makefiles already have proper prerequisites.
