[linux-riscv][J][PATCH] UBUNTU: SAUCE: scripts/Makefile.modinst discard-locals from modules

[Dimitri John Ledkov]

On riscv, it appears that all kernel modules are generated with an
excesive amount of local symbols and assembly automatic generated
symbols increasing the size of stripped .ko modules multiple times
over similar ones on other architectures. When stripping .ko on riscv,
discard these local symbols too, which should make our module sizes
somewhat more reasonable.

 This makes kernel install 863MB smaller, and everything appears to
 work fine. I.e. loaded btrfs module, mounted btrfs filesystem,
 unmounted it, etc.
