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

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.
