Makefile.toolchain: Switch from cpp to $(CC) -E
Makes it more straightforward to switch to clang preprocessor later
on.
This requires a few other modifications in the Makefiles (gcc -E does
not read from stdin by default, and does not process files that do not
end in .c/.h).
BRANCH=none
BUG=chromium:854924
TEST=make buildall -j
TEST=Before and after the change, all ec.bin binaries are identical:
git checkout m/master
make REAL_SIGNER=dummy buildall -j
mv build build-master
find build-master -type d | sed -e 's/-master//' | \
xargs -I{} mkdir -p {}
find build-master -name ec_version.h | sed -e 's|build-master/||' | \
xargs -I{} cp build-master/{} build/{}
git checkout this-cl
=> comment out .PHONY: $(out)/ec_version.h in Makefiles.rules
make REAL_SIGNER=dummy buildall -j
find build-master -name ec.bin | sed -e 's|build-master/||' | \
xargs -I{} diff build-master/{} build/{}
=> No difference
