Fix : libcanfestival_unix.a not built if examples are not compiled

Problem: when building Canfestival with unix timers 'libcanfestiva_unix.a'
is built only if you build examples too.

Test case:

$ ./configure --timers=unix --can=socket --target=unix
$ make canfestival

...

no errors but 'libcanfestival_unix.a' is not built:
$ find . -name "*.a"
./src/libcanfestival.a

Changing line 90 of 'drivers/unix/Makefile.in' to:
#driver: $(OBJS)
driver: libcanfestival_$(TARGET).a

solves the problem:

$ ./configure --timers=unix --can=socket --target=unix
$ make canfestival

...

$ find . -name "*.a"
./drivers/unix/libcanfestival_unix.a
./src/libcanfestival.a

HOW TO configure CanFestival for a CO-PCICAN card for linux:



pre-actions:
- install the CO-PCICAN card
- install and load the user space driver co_pcicanext.ko



- unpack the package to your target (if not already done)

- create empty file:
  touch /usr/local/lib/libcanfestival_can_copcican_linux.so

- perform package configuration:
  sh ./configure --can=copcican_linux

- build the CanFestival library:
  cd src
  make
  make install

- build the CanFestival Unix library:
  cd drivers/unix
  make
  make install

BUGFIX:
  copy library into build directory back:
  cp /usr/local/lib/libcanfestival_unix.a drivers/unix

- build the CO-PCICAN driver interface:
  cd drivers/can_copcican_linux
  make
  make install

- build the example application:
  cd examples/test_copcican_linux
  make

Run test_copcican_linux to see it works...
