[lazarus] lcl recompile hacks in makefiles

[Peter Vreman]

FYI: All the LCL recompile hacks can be removed when you include the line

[require]
options=-Ca

in the LCL Makefile.fpc

Also a 'make clean' tries to clean the designer dir that has no Makefile
yet.

And a last tip. Why is the 'allunits' a program? Having it also as a unit will
remove a the linking of the allunits program. The only thing you then have to
take care is that allunits.ppu / allunits.o aren't installed when creating a
make install target
