[bug#48275] gnu: ocaml: Depend on libiberty.

From: Ludovic Courtès <ludovic.courtes@inria.fr>

Currently gcc:lib does not include libiberty so this change restores the
initial intent.

* gnu/packages/ocaml.scm (ocaml-4.11)[inputs]: Replace "gcc:lib" by
"libiberty".

Hi there!

I noticed that “guix graph ocaml” looked weird; this change clarifies
the original intent.  In fact, the addition of gcc:lib was useless AFAICS:

--8<---------------cut here---------------start------------->8---
$ guix build -e '(@@ (gnu packages commencement) gcc-final)'
/gnu/store/01b4w3m6mp55y531kyi1g8shh722kwqm-gcc-7.5.0-lib
/gnu/store/rn75fm7adgx3pw5j8pg3bczfqq1y17lk-gcc-7.5.0
$ ls /gnu/store/01b4w3m6mp55y531kyi1g8shh722kwqm-gcc-7.5.0-lib/lib/*ibert*
ls: ne eblas atingi '/gnu/store/01b4w3m6mp55y531kyi1g8shh722kwqm-gcc-7.5.0-lib/lib/*ibert*': Dosiero aŭ dosierujo ne ekzistas
--8<---------------cut here---------------end--------------->8---

With this change I see that libiberty is indeed used while building
ocaml@4.11:

--8<---------------cut here---------------start------------->8---
../boot/ocamlrun ../boot/ocamlc -g -nostdlib -I ../boot -use-prims ../runtime/primitives -I .. -c -absname -w +a-4-9-41-42-44-45-48 -strict-sequence -warn-error A -principal -safe-string -strict-formats -bin-annot -I ../utils -I ../parsing -I ../typing -I ../bytecomp -I ../middle_end -I ../middle_end/closure -I ../middle_end/flambda -I ../middle_end/flambda/base_types -I ../driver -I ../toplevel -I ../file_formats -I ../lambda - opnames.ml
gcc  -O2 -fno-strict-aliasing -fwrapv -Wall -Wdeclaration-after-statement -fno-common -fexcess-precision=standard -fno-tree-vrp -ffunction-sections -o objinfo_helper objinfo_helper.o -lbfd -ldl  -liberty -lz
--8<---------------cut here---------------end--------------->8---

There’s no ‘-liberty’ in the build log of 4.09 though.

According to ‘guix refresh -l ocaml ocaml@4.09’, this change is OK
for ‘master’.

Thoughts?

Ludo’.

LGTM, thanks !
