Mohamed Gaber 1ded625f0f wheels: fix cmake argument passing 
- use CIBW_CONFIG_SETTINGS to pass cmake options
- disable homebrew for wheel build - bison is set explicitly
- update cmake option parsing to use shlex so multiple arguments can be provided
- use common CIBW environment (MACOSX_DEPLOYMENT_TARGET has no effect on linux)

Simon Bucher aa6108d70f kernel: handle EINTR and signal termination in run_command 
When `run_command` reads subprocess output via `fgets` in a multi-threaded process, incoming signals can interrupt the underlying `read` syscall with `EINTR`. Previously, `while (fgets(...) != NULL)` exited the read loop immediately on `EINTR` and called `pclose`, closing the pipe early while the child was still running (or causing the child to die with `SIGPIPE`). Additionally, `run_command` returned `WEXITSTATUS(ret)` without checking `WIFEXITED(ret)`, which evaluates to `0` when a child terminates due to an unhandled signal.

Retry `fgets` after clearing the stream error state when `ferror(f) && errno == EINTR`, and return `-1` if `!WIFEXITED(ret)`.

nella 3b7c09934a Materialize A sign extension in shiftadd. 
$shr and $shift sign-extend A to max(A_WIDTH, Y_WIDTH) before shifting.
shiftadd resliced A without that extension and left A_SIGNED set, so the
narrowed A was sign-extended a second time, from the wrong bit. Bake the
extension in before reslicing and clear A_SIGNED.

When the constant offset consumed all of A this also left an empty A on a
signed $shr, which techmap lowered to x.

Fixes #6214, fixes #6041.
