The 'clean' target is still noticeably slow on cygwin, despite the
improvements made by previous patches. For example, the second
invocation of 'make clean' below:

  $ make clean >/dev/null 2>&1
  $ make clean
  make[1]: Entering directory '/home/ramsay/git/gitweb'
  make[2]: Entering directory '/home/ramsay/git'
  make[2]: 'GIT-VERSION-FILE' is up to date.
  make[2]: Leaving directory '/home/ramsay/git'

has been timed at 10.361s on my laptop (on old core i5-4200M @ 2.50GHz,

Notice that the 'clean' target is making a nested call to the parent
Makefile to ensure that the GIT-VERSION-FILE is up-to-date. This is to
ensure that the $(GIT_VERSION) make variable is set, once that file had
been included. However, the 'clean' target does not use the $(GIT_VERSION)
variable, so this is wasted effort.

In order to eliminate such wasted effort, use the value of the internal
$(MAKECMDGOALS) variable to only '-include ../GIT-VERSION-FILE' when the
target is not 'clean'. (This drops the time down to 8.430s, on my laptop,
giving an improvement of 18.64%).
