Arch-depedently adding a minimum ocaml compiler requirement to unison:

[Ignatios Souvatzis <is%netbsd.org@localhost>]

Hello,

background: a while ago, I patched the native ARM backend of lang/ocaml
so that code generated by ocamlopt would not SIGILL on thumbless CPUs.

I've wanted to teach net/unison to use the native compiler also 
for arm. To make sure that only a sufficiently patched compiler is
used, I made it depend on ocaml>=3.12.0nb2

Should I change this to be architecture-dependent:

.if (${MACHINE_ARCH} == "arm")
BUILDLINK_ABI_DEPENDS.ocaml+=  ocaml>=3.12.0nb2
.else
BUILDLINK_ABI_DEPENDS.ocaml+=  ocaml>=3.08.2
.endif

or just leave it requiring 3.12.0nb2 globally?

Regards,
