This deals with the configure phase. It provides the configure action which is given the package description and configure flags. It then tries to: configure the compiler; resolves any conditionals in the package description; resolve the package dependencies; check if all the extensions used by this package are supported by the compiler; check that all the build tools are available (including version checks if appropriate); checks for any required pkg-config packages (updating the BuildInfo with the results)
Then based on all this it saves the info in the LocalBuildInfo and writes it out to the dist/setup-config file. It also displays various details to the user, the amount of information displayed depending on the verbosity level.

dist/setup-config
Makes a BuildInfo from C compiler and linker flags.
This can be used with the output from configuration programs like pkg-config and similar package-specific programs like mysql-config, freealut-config etc. For example:
ccflags <- rawSystemProgramStdoutConf verbosity prog conf ["--cflags"] ldflags <- rawSystemProgramStdoutConf verbosity prog conf ["--libs"] return (ccldOptionsBuildInfo (words ccflags) (words ldflags))
