From: Rong Xu <xur@google.com>

ChangeLog:

V5: Handle single quote escaping in echo _c_flags to fix
Piotr Gorski's reported error.

V4: This is based on the reimplementation provided by Masahiro Yamada
on May 26. The difference is that this version now saves the compiler
flags (_c_flags) from the Front-End (FE) compilation and re-uses them
for the subsequent Back-End (BE) compilation.

Rong Xu (2):
kbuild: move vmlinux.a build rule to scripts/Makefile.vmlinux_a
kbuild: distributed build support for Clang ThinLTO
