Cuirass Error while evaluating the specification

[Reza Alizadeh Majd]

Hi Guix, 

I want to build a series of packages using cuirass, I defined following sample 
definition as cuirass specification:

```
(list
  '((#:name . "pantherx-packages")
    (#:load-path-inputs . ("guix"))
    (#:package-path-inputs . ("guix"))
    (#:proc-input . "guix")
    (#:proc-file . "build-aux/cuirass/gnu-system.scm")
    (#:proc . cuirass-jobs)
    (#:proc-args . ((subset . "hello")))
    (#:inputs . (((#:name . "guix")
                  (#:url . "git://git.savannah.gnu.org/guix.git")
                  (#:load-path . ".")
                  (#:branch . "master")
                  (#:no-compile? . #t))
                 ))))
``` 

but when I execute cuirass, I receive following error: 

```
$ cuirass -S spec.scm -D test.db

Some deprecated features have been used.  Set the environment
variable GUILE_WARN_DEPRECATED to "detailed" and rerun the
program to get more information.  Set it to "no" to suppress
this message.
```

it seems that `icecat-gnuzilla-fixes.patch` file is removed from repository, 
but cuirass still looks for it during spec evaluation. and this issue shows 
itself from this commit in guix repository:

https://git.savannah.gnu.org/cgit/guix.git/commit/?id=34369f310319b040d18864ff7435b8ee5f9a26a6

could any one help about this issue?
