[fpc-pascal] shared library on arm-linux (raspberry pi)

[Fabio Luis Girardi]

I did more tests. If I try build a empty program linked with libc, this
program cause a linker failure as mentioned on previous message.

program program1;

{$LINKLIB c}

begin

end.

Someone can say if this is a problem with my raspbian image or a problem
with my FPC installation?
