[PATCH v4 0/2] kbuild: distributed build support for Clang ThinLTO

[xur]

From: Rong Xu <xur@xxxxxxxxxx>

This V4 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
