Subject: [PATCH v6 1/6] LoongArch: Add CONFIG_AS_HAS_EXPLICIT_RELOCS

GNU as >= 2.40 and GCC >= 13 will support using explicit relocation
hints in the assembly code, instead of la.* macros.  The usage of
explicit relocation hints can improve code generation so it's enabled
by default by GCC >= 13.

Introduce CONFIG_AS_HAS_EXPLICIT_RELOCS as the switch for
"use explicit relocation hints or not."
