LoongArch: Add Kconfig option AS_HAS_EXPLICIT_RELOCS
LoongArch inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I5OHOB
--------------------------------
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 a Kconfig option AS_HAS_EXPLICIT_RELOCS as the switch for
"use explicit relocation hints or not".
