FTBFS PHP 8.2 on Ubuntu 18.04 ppc64el

Description

The PHP 8.2.0 fails to build from source on Ubuntu 18.04 ppc64el:

/<<PKGBUILDDIR>>/ext/hash/xxhash/xxhash.h: In function ‘XXH3_accumulate_512_vsx’:
/<<PKGBUILDDIR>>/ext/hash/xxhash/xxhash.h:4148:9: error: invalid parameter combination for AltiVec intrinsic __builtin_vec_ld
         xxh_u64x2 acc_vec        = vec_xl(0, xacc + 2 * i);
         ^~~~~~~~~
/<<PKGBUILDDIR>>/ext/hash/xxhash/xxhash.h:4158:9: error: invalid parameter combination for AltiVec intrinsic __builtin_vec_st
         vec_xst(acc_vec, 0, xacc + 2 * i);
         ^~~~~~~

Full build log here: https://launchpadlibrarian.net/638336451/buildlog_ubuntu-bionic-ppc64el.php8.2_8.2.0-1+ubuntu18.04.1+deb.sury.org+1_BUILDING.txt.gz

I think it needs a refresh from upstream, the line that's causing problems is different in upstream xxHash: https://github.com/Cyan4973/xxHash/blob/dev/xxhash.h#L4689

xxh_u64x2 acc_vec        = (xxh_u64x2)vec_xl(0, xacc + 4 * i);

PHP Version

PHP 8.2.0
