lots of directory changes when compiling emacs..

[Alfred M\. Szmidt]

Hey,

Dunno if this is a "bug" or not, but when compilign emacs there are
lots of unneeded directory changes:

[...]
make[3]: Entering directory `/home/ams/emacs/lisp'
Compiling /home/ams/emacs/src/../lisp/mwheel.el
Wrote /home/ams/emacs/lisp/mwheel.elc
make[3]: Leaving directory `/home/ams/emacs/lisp'
make[3]: Entering directory `/home/ams/emacs/lisp'
Compiling /home/ams/emacs/src/../lisp/x-dnd.el
Wrote /home/ams/emacs/lisp/x-dnd.elc
make[3]: Leaving directory `/home/ams/emacs/lisp'
make[3]: Entering directory `/home/ams/emacs/lisp'
Compiling /home/ams/emacs/src/../lisp/widget.el
Wrote /home/ams/emacs/lisp/widget.elc
make[3]: Leaving directory `/home/ams/emacs/lisp'
[...]

this happens for each file in lisp/, and slows down compilation
considerably.
