Revert of Default-enable external startup data for Linux for stand-alone builds. (patchset #1 id:1 of https://codereview.chromium.org/956373002/)

Reason for revert:
The CL caused two issues:
- a weird build issue on V8 mips builder
- d8 cannot be invoked via PATH, since then it doesn't find its external snapshot.

The 2nd issue might even be WAI, but this needs more consideration.

Xcode uses a different naming scheme for directories within
the xcodebuild directory. But it is safe to just delete
everything withing xcodebuild or out. Keep the soft clobber
for windows' build directory only, where subdirectories
follow the *release* and *debug* naming scheme.

Without this change, it is non-trivial to know during
runhooks, if a landmine was just triggered in a checkout
that doesn't have the initial landmines script CL yet, i.e.
that didn't create a .landmines file yet.

This runs the landmines script as a gclient hook. It can
as such be used to clobber local checkouts when hooks are
run locally.

It is a softer version than chromium's landmines script, as
it only deletes directories in the output directory due
to compatibility with MSVS which has "build" hardcoded as
output directory in several places.

Contribution of PowerPC port (continuation of 422063005 and 817143002). This patch covers
the key changes needed to the common files needed to support AIX. Subsequent
patches will cover:
- changes to update the ppc directories so they are current with the changes
in the rest of the project.
- remaining AIX changes not resolved by 4.8 compiler
- individual optimizations for PPC

This is based off of the GitHub repository

number of bugs caused by 80-to-{32,64}-bit rounding errors. It's also

This relands parts of

It prepares for using this script outside of v8, e.g. in a
chromium hook.

The script is intended to run as a hook and will create
version_gen.cc if the content has changed.

Changes to gyp and gn files can land as a follow up, once
calling the hook on the chromium side has landed.
