From 4e56207130eda9a27df116623e2fce7cca2c6764 Mon Sep 17 00:00:00 2001 From: Douglas Anderson Date: Mon, 16 Oct 2017 10:12:46 -0700 Subject: kbuild: Cache a few more calls to the compiler These are a few stragglers that I left out of the original patch to cache calls to the C compiler ("kbuild: Add a cache for generated variables") because they bleed out into the main Makefile and thus uglify things a little bit. The idea is the same here, though.
