fix a major snafu that broke binary builds

don't leave the shared library path variable commented out in envvars for non-binbuild... OS/390 needs it set all the time

get binbuild to do the right thing with envvars (install/edit as appropriate) fix a problem in the load-library-path setting (wrong kind of quotes were used)

Move any load library path environment variables out of apachectl and into a separate environment variable file which can be more easily tailored by the admin. The environment variable file as built by Apache may have additional system- specific settings. For example, on OS/390 we tailor the heap settings to allow lots of threads.
