Jade Lovelace 68c99247bd Fix archive reproducibility 
The git archive export-subst option does not have consistent results
over time, since the abbreviated commit hash can get longer over time.

Instead, let's export the full commit hash.

This was found in an audit of source archive reproducibility in nixpkgs:

```
~ » expected=$(nix-store -r /nix/store/4j9rj4m6akjskp0f7k923qff817k6hv5-source)
actual=$(nix-prefetch-url --print-path --unpack --name source 896e5e7ded.tar.gz | tail -n1)
nix-shell -p diffoscope --run "diffoscope $expected $actual"
this path will be fetched (3.77 MiB download, 34.50 MiB unpacked):

Jannis Harder adbcb914b2 Add '-p' option to 'constr' to allow fully removing constraints 
Invoking 'constr -r' converts constraints into POs but does not fully
remove them. Now 'constr -pr' can be used to completely remove them,
leaving the set of non-constraint POs unchanged.

Mohamed A. Bamakhrama 15ec302095 Define S_IREAD|IWRITE macros using IRUSR|IWUSR 
On platforms such as Android, legacy macros are no longer defined.
Hence, we define them in terms of the new POSIX macros if the new ones are defined. Otherwise, we throw an error.

Sean Cross 10b9da7acb Makefile: break apart steps in `make clean` 
The `make clean` target consists of a single `rm` call that passes every
generated file, object file, and dependency directory.  This results in
a command line that's around 53,800 characters long.

On Linux, the maximum length of a command line is 131,072 or 262,144
characters, however on Windows the limit is 32,768.

The 53,800 character command simply fails to run on Windows, which is a
problem when the first command that gets run is `make clean`.

Break this target into steps, first removing the output files, then the
object files, then any generated garbage, and then the object depedency
directories.

This fixes `make clean` (and as a result yosys) on Windows.
