i compiled with
make VERBOSE=1 -j$(getconf _NPROCESSORS_ONLN)
on my Notebook (Intel Core i5, 8 Cores).
it takes ~2hours without the Addons.
the last time i compiled on L5 also with
make VERBOSE=1 -j$(getconf _NPROCESSORS_ONLN)
it run over night and presented me next morning
compilation failed caused by out of memory.
in this course of cross-compiling i learned to run make -j1 only in case of errors!. i re-run it with -j1 and see the error more easily.
otherwise you have to have a lot of time
