Message:

loongarch: kernel: Apply an upstream fix for Binutils 2.42

Though the commit message mentions "recent Binutils and GCC trunk", I'm
99.99% sure this is only related to Binutils since the troubling
R_LARCH_RELAX/R_LARCH_ALIGN is appearing in some object files assembled
from .S files.

IMO this commit should be backported to even 6.1, but Huacai always
believe people using the latest Binutils should use the latest kernel.
And it seems Linux 6.8 won't catch LFS 12.1 package freeze, leaving me
no choice but backporting this downstream.
