So MIPS EFI file would come with .rodata section. If we don't preserve
it here, the whole section would be stripped away.

.rodata is always necessary in binary if it's in ELF as it contains
valid program data.

Other architectures won't generate .rodata section in their ELF file
so it's harmless. Besides GNU-EFI's universal strip commands also have
-j .rodata argument.
