Refactor config - @MK1MF_Builds out, general build scheme in
Time to get rid of @MK1MF_Builds and introduce a more flexible
'build_scheme' configuration key. Its value may be a string or an
array of strings, meaning we need to teach resolve_config how to
handle ARRAY referenses.
The build scheme is a word that selects a function to create the
appropriate result files for a certain configuration. Currently valid
build schemes aer "mk1mf" and "unixmake", the plan is however to add
at least one other for a more universal build scheme.
Incidently, this also adds the functions 'add' and 'add_before', which
can be used in a configuration, so instead of having to repeatedly
write a sub like this:
key1 => sub { join(" ", @_, "myvalues"); },
key2 => sub { join(" ", "myvalues", @_); },
one could write this:
key1 => add(" ", "myvalues"),
key2 => add_before(" ", "myvalues"),
The good point with 'add' and 'add_before' is that they handle
inheritances where the values are a misture of scalars and ARRAYs. If
there are any ARRAY to be found, the resulting value will be an ARRAY,
otherwise it will be a scalar with all the incoming valued joined
together with the separator given as first argument to add/add_before.
