bug#18262: perl-tk intermittent failures due to parallel build

[mhw]

perl-tk intermittently fails with error messages that suggest that it
is related to the build being done in parallel.  For examples, see:

  http://hydra.gnu.org/build/58535/log/tail-reload
  http://hydra.gnu.org/build/82185/log/tail-reload

I tried to add #:parallel-build #f to the arguments, but that flag seems
to be unsupported in the perl-build-system, even though it is almost
identical to the gnu-build-system.

I think the following (untested) patch adds support for the flag:

diff --git a/guix/build-system/perl.scm b/guix/build-system/perl.scm
index 5695491..515ca90 100644
--- a/guix/build-system/perl.scm

                    #:tests? ,tests?
+                   #:parallel-build? ,parallel-build?
                    #:outputs %outputs
                    #:inputs %build-inputs)))
 
If it does, we might add #:parallel-tests? at the same time.

Yes, indeed.

Yes.

Could you do it?

Thanks,

Commit cb150ca changes perl-tk to build sequentially, which should solve
this issue.
