Unless specified otherwise, the default package set compiles library variants
for profiling with profiling-detail "all-functions". Executables, however, are
not built with profiling enabled.
This change increases the closure size for many Haskell programs, but the
practical advantage of having stack traces and performance measurements easily
available during development seems to outweigh that cost.
