perl: split perl-cross into its own recipe

As perl and perl-cross need to be updated (and patches rebased)
in lockstep, devtool upgrade (and therefore AUH) can't cope with it.
Manually updating is still possible, but painful.

Split determinism.patch into perl and perl-cross parts, move the
rest of the perl-cross patches.

+**perl-cross** provides configure script, top-level Makefile
+and some auxiliary files for [perl](http://www.perl.org),  
+with the primary emphasis on cross-compiling the source.

+    curl -L -O http://www.cpan.org/src/5.0/perl-5.24.1.tar.gz
+    curl -L -O https://github.com/arsv/perl-cross/releases/download/1.1.3/perl-cross-1.1.3.tar.gz

+    ./configure --target=arm-linux-gnueabi --prefix=/usr -Duseshrplib
+    make -j4
+    make DESTDIR=/path/to/staging/dir install
+
+Unlike mainline Perl, this configure never runs any target executables,  
+relying solely on compile/link tests and pre-defined hints.  
+On the flip side, it is only meant to run on resonably sane modern unix systems.  
+
+Check [project pages](http://arsv.github.io/perl-cross/) for more info.  
+In particular, [configure usage](http://arsv.github.io/perl-cross/usage.html)
+lists available configure options.
+
+Perl-cross is a free software licensed under the same terms
+as the original perl source.

+Fixes to make the perl build reproducible:
+
+a) Remove the \n from configure_attr.sh since it gets quoted differently depending on
+   whether the shell is bash or dash which can cause the test result to be incorrect.
+   Reported upstream: https://github.com/arsv/perl-cross/issues/87
+
+b) Sort the order of the module lists from configure_mods.sh since otherwise
+   the result isn't the same leading to makefile differences.
+   Reported upstream: https://github.com/arsv/perl-cross/issues/88
+
+c) Sort the Encode::Byte byte_t.fnm file output (and the makefile depends whilst 
+   there for good measure)
+   This needs to go to upstream perl (not done)
+
+d) Use bash for perl-cross configure since otherwise trnl gets set to "\n" with bash
+   and "" with dash
+   Reported upstream: https://github.com/arsv/perl-cross/issues/87
