Revert "Rename target-specific binaries built for host."

The Android build system support for gyp has been fixed to handle
target-dependent host binaries correctly without requiring them to
include the target architecture in the name. Remove the suffixes to make
referring to these targets simpler again.

This reverts r14209.

Hi Jakob,

I'd like to undo the change I made some time ago to include the target
architecture in the names of the v8 targets; I've since fixed the gyp-android
backend to not require this any more, and it makes it difficult to write
downstream Android modules that depend on V8 because you have to refer to
different things depending on the architecture.

If this is okay, can you land it for me? :)

Ping; Jakob, can we go ahead with this? It'd help me clean some stuff up in
Android..

LGTM, landing.

Hi Jakob,

There's a target which still has the architecture in the name; it was introduced
after I originally prepared this patch :)

Can you rename v8_libbase.<(v8_target_arch) to v8_libbase ? We need to depend on
this as well since code is moving into it from v8_base, and so right now we're
having to go back to having architecture-specific dependencies :/
