[Patch, AARCH64] gc-section support

[Yufeng Zhang]

Hi Venkat,

Thanks for the patch.

Can you please generate the patch using "diff -u -p"?  This will make 
the patch easier to review.  Also the indent is not consistent with the 
existing style, which is hard tab(s) plus spaces.  Can you please 
correct it as well.

Thanks,
Yufeng
