bug#33737: do not attempt to build a package known to be broken

[znavko]

Package can have additional fields in guix repository, like

architecture, version, buid_status, source_type

build_status may contain such info.

source_type could show if the package source url is one of those public git services (thus, user could enable proxy first).

The default use case is for users to have substitutes enabled and to

fetch binaries from a build farm. The build farm tries to build all

packages, but not all builds succeed. The daemon caches build

failures.

This information, however, is not available for users. The default

behaviour of Guix is to attempt building the package locally. This is

fine for packages that the build farm hasn’t attempted yet, but it is

a waste of time when the build has already been attempted without

success.

+1

Very good idea.
