When CONFIG_ULIB is enabled for cross-compiled EFI builds, some
built-in.o archives are empty (e.g. arch/riscv/cpu/generic/built-in.o
for efi-riscv_app64). The objcopy --redefine-sym command fails on
empty files.

Skip them by checking the file size before calling objcopy, producing
an empty output file to keep the archive list consistent.
