ocaml: fails to build on 10.6 and lower

[mojca (Mojca Miklavec)]

OCaml port fails to build on 10.6 and lower. It might help to use a newer compiler, but it makes sense to test the hypothesis before blindly adding items to compilers blacklist.

/usr/bin/gcc-4.2 -c -DSYS_macosx -DMODEL_default -o amd64.o amd64.S || \
	{ echo "If your assembler produced syntax errors, it is probably";\
          echo "unhappy with the preprocessor. Check your assembler, or";\
          echo "try producing amd64.o by hand.";\
          exit 2; }
amd64.S:708:Unknown pseudo-op: .string
amd64.S:708:Rest of line ignored. 1st junk character valued 34 (").
If your assembler produced syntax errors, it is probably
unhappy with the preprocessor. Check your assembler, or
try producing amd64.o by hand.

If it turns out that it in fact cannot be built, the port should at least say so. But I guess it's just an issue with too old compiler.

On 10.5 it failed with
