Description
Since 2025-06-20, std does not build on AIX: https://does-it-build.noratrieb.dev/target?target=powerpc64-ibm-aix
There are a variety of errors around libc: https://does-it-build.noratrieb.dev/build?nightly=2025-07-04&target=powerpc64-ibm-aix&mode=miri-std

Research direction
Start with library/std/src/os/aix/fs.rs, library/std/src/sys/fd/unix.rs, library/std/src/sys/fs/unix.rs, library/std/src/sys/net/connection/socket/unix.rs, and library/std/src/sys/process/unix/unix.rs, using the reported AIX errors as the entry point. Rebuild std for powerpc64-ibm-aix and verify that the libc field, ioctl, and setgroups errors no longer prevent the sysroot from building.
