I doubt it. There was some discussion here:

https://www.mail-archive.com/bug-gnulib@gnu.org/msg41057.html

I'm cc-ing Paul Eggert for additional considerations about this, but at the moment it seems the safest
is to just use 32-bit time_t for 32-bit hosts. There were some concerns about breaking compatibility if
we moved to 64-bit time_t on 32-bit hosts.

Maybe the best course of action is to get autoconf patched to support year2038 checks and then use that
in binutils-gdb.
