This intentionally diverges from the unix dirname command, as well as
Python and Node.js standard libraries, which all have this edge case
return the input path, unmodified. This is a footgun, and nobody should
have ever done it this way.
Even the man page contradicts the behavior. It says:
"strip last component from file name". Now consider, if you
remove the last item from an array of length 1, then you
have now an array of length 0. After you strip the last component, there
should be no components remaining. Clearly, returning the input parameter
unmodified in this case does not match the documented behavior. This is
my justification for taking a stand on this API design.

raise the timeout to 100ms to be sure that if it fails (timeout is returned) it is due to a real problem.
the test shouldn't be longer: it will wait more time only on failure.
As documented in the comment right above the finalization function,
Gimli can be used as a XOF, i.e. the output doesn't have a fixed
length.
So, allow it to be used that way, just like BLAKE3.
With the simple rule that whenever we have or will have 2 similar
functions, they should be in their own namespace.
Some of these new namespaces currently contain a single function.
This is to prepare for reduced-round versions that are likely to
be added later.
It is now possible to force linking with system linker `ld` instead
of the LLVM `lld` linker when building natively on the target. This
can be done at each stage by specifying `--system-linker-hack` flag,
and can be useful on platforms where `lld` fails to operate properly
such as macOS 11 Big Sur on ARM64 where every binary/dylib is expected
to be codesigned.
Some example invocations for each stage of compilation of Zig
toolchain:
```
cmake .. -DCMAKE_PREFIX_PATH=/path/to/llvm -DSYSTEM_LINKER_HACK=1
```
```
build/zig build test --system-linker-hack
```
```
build/zig build --prefix $(pwd)/stage2 -Denable-llvm
--system-linker-hack
```
```
build/zig build-exe hello.zig --system-linker-hack
```
Comparisons with absolute epsilons are usually useful when comparing
numbers to zero, for non-zero numbers it's advised to switch to relative
epsilons instead to obtain meaningful results (check [1] for more
details).
The new API introduces approxEqAbs and approxEqRel, where the former
aliases and deprecated the old `approxEq`, allowing the user to pick the
right tool for the job.
The documentation is meant to guide the user in the choice of the
correct alternative.

There's no guarantee for the kernel definition to be ABI compatible with
the libc one (and vice versa).
There's also no guarantee of ABI compatibility between musl/glibc.
Fun, isn't it?
