Ok, what is happening here ? 
The message clearly states that the compiler tries to recompile the system
units. This is BAD. it means that it found sources that are newer than the 
units in /usr/lib/fpc/etc.
This is natural, because ../rtl/linux is in the units path.

1) The compiler will look in the directory ../rtl/linux for the system units.
2) The compiler will look in the directory ../fcl/linux for the classes stuff.
3) The compiler will look in the directory ../gtk for gtk stuff.
4) the compiler will look in the directory ../lazarus for lazarus stuff.

Now, 2 depends on 1
     3 depends on 1
     4 depends on 2 and 1 and 3

So the following should build everything;
  cd rtl/linux
  make clean; make
  cd ../../fcl/linux
  make clean; make
  cd ../../gtk
  make clean; make
  cd ../lazarus
  make clean; make
  cd ../hello_world
  make

These are the _EXACT_ steps as I do them every day; apart from errors in the
source code, this has never failed me. 

I suggest you try this.

Michael.
