[fpc-pascal] Silencing redundand FPC messages

[Lubos Pintes]

Hello,
I am compiling from command line. I am screen reader user relying on 
spoken output. I would like to minimize the output as much as possible, 
especially if the output is redundant.
FPC outputs are concise and clean IMO, but some always-repeating things 
it outputs are just useless. One can be avoided by -l- switch. But how 
can I get rid of "Target OS XXX:"?
Thanks
