[ Upstream commit 4ab2ee307983548b29ddaab0ecaef82d526cf4c9 ]
Currently, when cross-compiling and ccache is used, the expanding of CC turns out to be without any quotes, leading to the following error:
make[4]: *** No rule to make target 'aarch64-linux-gnu-gcc'. Stop. make[3]: *** [Makefile:2164: run-command] Error 2
And it makes sense, because after expansion it ends up like this:
make run-command KBUILD_RUN_COMMAND=+$(MAKE) \ HOSTCC=ccache aarch64-linux-gnu-gcc VPATH= srcroot=. $(build)= ...
So add another set of double quotes to surround whatever CC expands to to make sure the aarch64-linux-gnu-gcc isn't expanded to something that looks like an entirely separate target.
