sb: Support --dry-run --with-download for 3rd party RTEMS BSP packages.

The building of 3rd party packages for an RTEMS BSP requires a valid
BSP so the standard method to download the source for releasing does
not work. This change adds support to allow this. The RTEMS BSP support
will not generate an error is no BSP or tools are provided or found.

The change addis logic operators to the %if statement so you can '
'

to 'or' and '&&' to 'and' logic expressions.

A new %log directive has been added to clean up the messages.

A new %{!define ...} has been added to aid checking within logic
expressions.

All command line --with/--without now appear as macros.

Add version.version to get just the RTEMS major and minor version.

Some pkg-config issues have been resolved.

Closes #2655.
