[PATCH v8 2/3] kbuild: change --thin back to 'T' in $(AR)

[xur@google.com]

From: Rong Xu <xur@google.com>

The '-T' flag in $(AR) is no longer problematic since the minimum
requirement for LLVM has been updated to version 15. As of LLVM 14
and onward, the '-T' flag functions identically to the '--thin' flag.

Fixed the issue seen on IBM Power11 System:
  ar: unrecognized option '--thin'

Closes: https://lore.kernel.org/linux-next/476507c9-a371-4864-9e87-572c1ecae82d@linux.ibm.com/
