@pmur requested issue #68957 to be considered for backport to the next 1.22 minor release.

@gopherbot please consider this for backport to 1.22 and 1.23, this is a bug with no workaround.

[release-branch.go1.22] runtime: on AIX, fix call to _cgo_sys_thread_…
e87be98 
…create in _rt0_ppc64_aix_lib

The AIX ABI requires allocating parameter save space when calling
a function, even if the arguments are passed via registers.

gcc sometimes uses this space. In the case of the cgo c-archive
tests, it clobbered the storage space of argc/argv which prevented
the test program from running the expected test.

Fixes #68972
