Linux can now be built with LLVM=1, all necessary llvm params
such as CC, LD, OBJCOPY, and NM will be set correctly.
Introduce LLVM=1 to kenv.mk and drop legacy approach.
To make it work, we have to also change build.config.mtk* files.
With commit commit 2c71673913c12528c77bd0f75ce2c6adc9ac5059
("Revert "ANDROID: Kbuild, LLVMLinux: allow overriding clang target triple""),
we must not use "CLANG_TRIPLE" in build commands, otherwise well
have boot failures.

Comment out DEFCONFIG in build.config.mtk* to pass DEFCONFIG
from command line. We can use build.config.mtk* to test
different internal kernel configs.

Remove functions from build.config.mtk. This is the preparation
for "include the build.config.mtk files" in the kenv.mk.
kenv.mk is a Makefile so we have to make build.config.mtk compatible
with kenv.mk.
