[issue18493] make profile-opt fails with pre-existing python2.7 in path

[Zachary Ware]

Zachary Ware  added the comment:

This was fixed in 3.x in 2015 and later backported to 2.7 in 2017.  Thanks for 
the report, Claudio, and I'm sorry nobody noticed this earlier or we could have 
fixed the issue two years earlier!

[issue18493] make profile-opt fails with pre-existing python2.7 in path

[Claudio Freire]

New submission from Claudio Freire:

When building with --enable-shared in an environment that already has a 
python2.7 (and I'd expect the same to happen to 3.x), make profile-opt fails 
because it attempts to load the existing libpython instead of the just-built 
one.

run_profile_task should use RUNSHARED. In fact, it builds fine if $(RUNSHARED) 
is added to that line.

Patch inline below, for 2.7.5:
