[Click] soft bug in click Makefile

[Angelo Marletta]

when running make install, for installing click as a kernel module, from a 
directory that contains at least one space in its absolute path, program 
exits with this error:

/bin/ln -s `cd .; pwd` /usr/local/share/click/src
/bin/ln: quando si fanno link multipli l'ultimo argomento deve essere una 
directory
make[1]: *** [install-local] Error 1
make[1]: Leaving directory `/home/angelo/universita/reti di 
calcolatori/tesina/click-1.4.1'
make: *** [install] Error 2

to solve the problem edit line 70 of Makefile

/bin/ln -s `cd $(top_srcdir); pwd` $(clickdatadir)/src

to

/bin/ln -s "`cd $(top_srcdir); pwd`" $(clickdatadir)/src
