Found this missing error reporting when a user was trying to run Netsurf and it wouldnt load.
With some debugging, and realizing that the main() function was not called, finally I figured out it's because of loading the libc.dll
With this change in contrib/toolchain/, the users who run C applications and dont have a libc.dll will see an error message in the DEBUG BOARD.

I've Pushed this to SVN as well.
