elf: Fix compile error with -Werror and -DNDEBUG
Using -Werror and -DNDEBUG at the same time will trigger the following compiler error: cache.c: In function 'save_cache': cache.c:758:15: error: unused variable 'old_offset' [-Werror=unused-variable] 758 | off64_t old_offset = lseek64 (fd, extension_offset, SEEK_SET); | ^~~~~~~~~~ -DNDEBUG disables the assertion, making old_offset unused. Use __attribute__ ((unused)) to disable this warning.
