Yes, the default system linker's built-in linker script contains the  
search path for all system libraries. That is the reason why we don't  
use the "-T" option the linker complains about, because doing so would  
tell the linker to ignore the built-in linker script and hence also  
those system-specific library search paths.

We could also very easily get rid of the -T warning by getting rid of  
all the built-in linker scripts in the compiler, and replacing them  
with just the parts that are FPC-specific (basically keeping the  
".fpc" section), but for reasons I still don't understand some people  
think this would cause problems.

The only argument in favour of keeping the compiler-internal linker  
scripts for Linux targets that I currently can think of is that it  
would probably make the built-in ELF linker harder to realise (it  
would probably have to ask the system linker for the default linker  
script then). We could also let the internal linker use a compiler- 
internal linker script and the external linker the system default one,  
but that's probably not a good idea (ideally the internal and external  
linker would use the same settings, both from a support and from a  
predictability perspective).
