Did this for two reasons:
1. Easier to read incremental output this way
2. I believe that, with incremental builds, we were running out of file
descriptors in some cases due to so rapidly plowing through all of the
packages. I'm not certain this was the source of the errors I was
seeing, but given (1), it made sense to try this first.
Previously, package install status was determined by checking the
package database. However, this didn't work for executables, so I
switched it to keep explicit track of build results. I forgot to then
clear those results when unregistering a package.

* Implements --enable-library-profiling in the executable
* Adds pbEnableLibProfiling
* Adds ability to skip profiling on some packages, e.g.

- transformers-compat
