Revert "ANDROID: Kbuild, LLVMLinux: allow overriding clang target triple"

This reverts commit e145f7b10374662f03889c2dea0fdc14df7f1371.

AOSP's distribution of GNU binutils always had a curious target triple
prefix on the binaries.  Now that GNU binutils is deprecated for Android
Common Kernels, we can now remove this out of tree workaround. Now
building Android kernels with LLVM matches upstream (see
Documentation/kbuild/llvm.rst).
