[FLASH-USERS] "relocation truncated to fit" error

[Brock Palen]

-mcmodel=medium will fix it,  you just need to make sure every  
library that is giving that error is compiled with it.  You also need  
to make sure that the final link also has the option or you will get  
that error.

Also blocks=100 sounds like a problem to me, not being a flash users  
(sys admin) others will need to comment.
