devel/ocaml-opam: pass correct $(CC) value to the bootstrap script

Otherwise it could be guessed wrongly and the build would fail, as
happens e.g. when ccache(1) tarball is extracted under /opt in the
build jail (tinderbox).

devel/ocaml-opam: Unbreak fetch

Upstream re-rolled the distfile with same name, and changed the name
of the extracted directory as well.  This requires the use of
DIST_SUBDIR to avoid fetch clash with previous.  Also revbump because
it's not clear if those were the only changes between distfiles.

devel/ocaml-opam: Upgrade version 1.2.0 => 1.2.1

PR:		199413
Submitted by:	mmatalka (gmail)
Revised by:	maintainer (Joris Giovannangeli)

Update USE_GITHUB so it does not require GH_COMMIT.

Using this new scheme allows only setting the _tag_ or _commit hash_ in
GH_TAGNAME and not having to know the hash for a tag.  This scheme will
download a tarball that has a different checksum than before due to a changed
directory name for extraction.

The following MASTER_SITES are provided to retain the old checksum and
directory structure (that require GH_COMMIT):
  GH -> GHL
  GITHUB -> GITHUB_LEGACY

devel/ocaml-opam: Upgrade version 1.1.1 => 1.2.0

Add several options for protocols such as rsync, git, wget, Hg, etc,
where the first three options are on by default.

devel/ocaml-opam: Update 1.1.0 -> 1.1.1 and unbreak

Updating to the latest point version did not fix the problems.  The
first is that now the built tool ocp-build requires TERM to be set in
the environment, otherwise it returns non-zero result with an error
message (hidden by /dev/null in first instance) and breaks the build.

Later the build failed the FS because it was saving preferences at $HOME.
Adding -no-user-prefs switch to the command seems to suppress that.

Finally, the GNU makefile is not jobs safe, so indicate that.  The GNU
makefile does not participate much in the overall build.

devel/ocaml-opam: Update to versions from 1.0 to 1.1

This also has benefit of fixing the problem where a .conf file was
created in ${HOME} which is illegal and the reason ocaml-opam never
made it into dports.  The original complaint of the PR could not be
reproduced, however.
