[Patch mach-o 3/3] section directives needed to support GCC

[Iain Sandoe]

Hi Tristan,

Thanks for reviewing the three patches - apologies that the first one  
was so  large.
... I would normally try to make smaller bites - but I guess I felt  
that it did all belong together (a lot of the bulk is in repetitive  
table stuff).

Do you wish me to repost after rebasing and addressing your points -  
(or I could send to you as a diff, if you intend to apply it).

I didn't do that because ISTM that we can't tell the difference  
between gas inserting them by default - and the User intentionally  
defining them as empty (for some devious reason).

I suppose we could keep track of whether the User does define them....

WDYT?
