Subdirectories built different number of times

[Brad Lucier]

I decided to try to see how many times each subdirectory of gcc
was entered during a bootstrap, since it seemed to me that the java
subdirectory was entered more then the others, and got:

popov-10% grep 'Entering.*java' build.log 
make[3]: Entering directory `/export/u11/lucier/programs/egcs/objdir/gcc/java'
make[3]: Entering directory `/export/u11/lucier/programs/egcs/objdir/gcc/java'
make[3]: Entering directory `/export/u11/lucier/programs/egcs/objdir/gcc/java'

popov-12% grep 'Entering.*\/ch' build.log
make[3]: Entering directory `/export/u11/lucier/programs/egcs/objdir/gcc/ch'
make[3]: Entering directory `/export/u11/lucier/programs/egcs/objdir/gcc/ch'
popov-20% grep 'Entering.*\/f' build.log
make[3]: Entering directory `/export/u11/lucier/programs/egcs/objdir/gcc/f'
make[3]: Entering directory `/export/u11/lucier/programs/egcs/objdir/gcc/f'
popov-21% grep 'Entering.*\/ch' build.log
make[3]: Entering directory `/export/u11/lucier/programs/egcs/objdir/gcc/ch'
make[3]: Entering directory `/export/u11/lucier/programs/egcs/objdir/gcc/ch'

Is this correct?  I can understand that maybe cp is entered more times
than some others since some libraries might require cp to be built,
but should java be entered more times than /cp?

This is on alphaev6-unknown-linux-gnu, configured with

--prefix=... --enable-checking=no

and made with make-3.79 with "make -j bootstrap".
