Add riscv32-specific '__ashldi3()', '__ashrdi3()', and '__lshrdi3()'. Initially it was intended to fix the following link error observed when building EFI-enabled kernel with CONFIG_EFI_STUB=y and CONFIG_EFI_GENERIC_STUB=y: riscv32-linux-gnu-ld: ./drivers/firmware/efi/libstub/lib-cmdline.stub.o: in function `__efistub_.L49': __efistub_cmdline.c:(.init.text+0x1f2): undefined reference to `__efistub___ashldi3' riscv32-linux-gnu-ld: __efistub_cmdline.c:(.init.text+0x202): undefined reference to `__efistub___lshrdi3' Reported at [1] trying to build https://patchew.org/linux/20260212164413.889625-1-dmantipov@yandex.ru, tested with 'qemu-system-riscv32 -M virt' only.
