In Linux kernel 5.14 one can dynamically request size of altstacksize based on hardware capabilities with getauxval(AT_MINSIGSTKSZ). This changes allows for Python extension's request to Linux kernel to use AMX_TILE instruction set on Sapphire Rapids Xeon processor to succeed, unblocking use of the ISA in frameworks. Introduced HAVE_LINUX_AUXVEC_H in configure.ac and pyconfig.h.in Used cpython_autoconf:269 docker container to generate configure. (cherry picked from commit 3b128c0)
