* when RELEASE=1, also perform two compilations of the compiler/rtl with WPO

(and use the resulting compiler as final compiler to compile the rest of
     the source tree and to install)

   Note: this means that if you manually use "make cycle RELEASE=1", the RTL
     afterwards will not be usable, because it will have been compiled with
     WPO for the compiler; if you use "make all" in the root FPC dir, there
     is no problem since that makefile recompiles the RTL anyway.
