Try "make clean && make" just in the hello directory. My normal work flow is:
* bootstrap rtems (one time)
* configure rtems (one time): use --enable-maintainer-mode, and other
configure options you want e.g. --enable-tests, etc
* build rtems (one time): make at the root of the build tree

Then when I modify the Makefile.am or configure.ac files I will rerun
bootstrap -p && bootstrap just from the directory with the
configure.ac, and then "make" in the root of rtems build should only
configure and update the dependent files.

When I modify source code files that exist, I can just type "make" to
rebuild rtems. However, the test suite applications are not dependent
on the libraries, sas pointed out by Sebastian, so I also will "make
clean" in testsuites (or whichever test suite I want to run, e.g.
samples, or just hello) and then "make".
