MFC r238038:

Unfortunately the change in r237958 resulted in s/install/instclean/ due to
the aggressive pattern matching of the :C modifier. I tested build and
install in 2 phases, however with different solutions, resulting in the
breakage. Mea culpa.

The solution is to break out the all: target. This causes a few lines of
code duplication, but now the all: target works as it should, and the
other targets continue to work as they did before.

While I'm here, add a ===> header line to the start of each port build
to make it easier to find/more clear in the logs.
