Add support for prefix and gitsrc arguments to 'make'

This should improve the installation a little, especially since the new
options are mentioned in the README. Also, add a make-rule to build the
git binaries if necessary + a dependency between cgit and libgit.a.

 Installation
 
-$ $EDITOR Makefile
-$ make
-$ sudo make install
+  $ make gitsrc=<path>
+  $ su
+  $ make prefix=<path> install
 
-Note: cgit requires the git and xdiff libraries. Currently, the makefile
-expects these files to be found in '../git/libgit.a' and '../git/xdiff/lib.a',
-where they will be if you have built git from source in a parallell directory.
+
+Default value for gitsrc is "../git", and this directory should contain the
+git sources.
+
+Default value for prefix is "/var/www/htdocs/cgit". This directory will 
+contain "cgit.cgi" and "cgit.css" after 'make install'.
+
+After installation, httpd.conf probably must be updated with a Directory-
+section for cgit, possibly something like this:
+
+  <Directory "/var/www/htdocs/cgit/">
+      AllowOverride None
+      Options ExecCGI
+      Order allow,deny
+      Allow from all
+  </Directory>
