1236,config/auto/format.pm:  Replace direct dependence on Perl 5 %Config,jkeenan,jkeenan,"In the course of working on TT #1189, I have had occasion to search for files, in the configuration system or elsewhere, which depend unnecessarily on the Perl 5 `%Config` found on the system where Parrot is being built.  I will be opening additional tickets for cases where I find such dependencies in files outside the configuration step tests.

''config/auto/format.pm'' does a direct lookup on Perl 5's `%Config` to determine one value:
{{{
     18 use Config;  # for long double printf format
...
     73     elsif ( $nv eq ""long double"" ) {
     74 
     75         # Stay way from long double for now (it may be 64 or 80 bits)
     76         # die ""long double not supported at this time, use double."";
     77         $nvsize   = $ldsize;
     78         if (defined($Config{'sPRIgldbl'})) {
     79             $nvformat = ""%.15"" .  $Config{'sPRIgldbl'};
     80             $nvformat =~ s/""//g;   # Perl 5's Config value has embedded         double quotes
     81         }
}}}
This is bad.  We eventually want to eliminate our dependence on `%Config` completely.  Until that time, we should at least do in this configuration step what we have done in all other configuration steps:  use an indirect lookup by going to `init::defaults` and placing a value in a special part of the Parrot::Configure object.

I opened the ''auto_format_no_Config'' branch to work on this.  Please see attached patch, which will I will apply in 3-4 days unless there is serious objection.

Thank you very much.
