Description of change

Issue #7500

AIX linker has a table of contents with default size 64K
The recent code inclusions in V8 brings in lot of new
symbols which necessitates to increase this default.

Please note that the debug build already has this flag

Does that mean the -Wl,-bbigtoc,-bE:<(PRODUCT_DIR)/node.exp in node.gyp can be removed now or is that still necessary?

[gireeshpunathil]

@bnoordhuis - I will check and get back on this.

[gireeshpunathil]

@bnoordhuis - you are right, the -bbigtoc flag in node.gyp is meant for the same purpose, but covers only the building of node. Now that the same is introduced in common.gypi, we don't need it in node.gyp any more. Please note however, that the -bE:<(PRODUCT_DIR)/node.exp needs to be retained.

And hence I have revised my changes. Please review and let me know.

[mhdawson]

Ok, toc issue resolve, and see new issue, will open separate issue for that one closing

@mhdawson lts?

[MylesBorins]

needs to land if #6734 lands

[mhdawson]

Id say if needed due to other commits, yes, otherwise if it applies cleanly then it probably makes sense just to avoid problems in the future.
