zicond is now codegen supported in both llvm and gcc.
This change allows seamless enabling/testing of zicond in downstream
projects. e.g. currently riscv-gnu-toolchain parses elf attributes
to create a cmdline for qemu but fails short of enabling it because of
the "x-" prefix.

When writing the upper mtime, we should keep the original lower mtime
