Trouble with building multilib GCC (MinGW)

I just now noticed that xgcc is used.
According to the instructions [1], core-cross-compiler (make all-gcc)
must be built first, and with its help multilib-crt and gcc (make all)
is built. How is it possible to determine that xgcc runs/uses
<sysroot>/bin/i686-w64-mingw32-gcc.exe? After building and
installation (make all-gcc & make install-gcc) core-cross-compiler, I
set <sysroot>/bin in PATH.
