[PATCH master] ci: container: set LLVM_SUFFIX instead of CROSS_COMPILE_llvm

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

To compile with LLVM inside the container, the expectation so far was
that the user would do:

  export LLVM="${CROSS_COMPILE_llvm}"

This is confusing as CROSS_COMPILE is gcc-only and needlessly
cumbersome. The Makefile also accepts LLVM_PREFIX and LLVM_SUFFIX
variables. The utilities are already in PATH, so just set LLVM_SUFFIX to
the correct. -${LLVM_VERSION} suffix.

Users will then have to only set

  export LLVM=1

and GCC builds continue to be unaffected as LLVM_SUFFIX/PREFIX are only
evaluated if ${LLVM} is non-empty.
