Actually this patchset is a combination of "Update to gdb-16.2" and
"Fix several build failures".
The reason for the patchset combination is, the latter one backported
several gdb upstream patches[1], which is not needed after the gdb upgrade.
It is meaningless to backport and revert the patch in a short time, so I
merged them into 1 patchset.
For patchset "Fix several build failures", patch 1 is elimited, patch 2
is untouched, and patch 3 is slightly modified for adaption.

New subject: [PATCH 1/5] Revert: Fix C99 compatibility issues in embedded copy of GDB
The related gdb commits mentioned in the original patch has been
integrated in gdb v16.2, so revert it for gdb rebase preparation.

New subject: [PATCH 2/5] Revert longaarch related gdb changes
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")
