This commit will revert the gdb specific changes of longaarch [1][2]. Same as
the previous patch, the longaarch related gdb changes have already been
integrated in gdb v16.2, so no longer needed and should be reverted.
[1]: 35a2472e7a3087 ("Add LoongArch64 framework code support")
[2]: 3f205d1d4af5a1 ("LoongArch64: Fixed link errors when build on
LOONGARCH64 machine")
