this is quite annoying for cmake-detecting things, as cmake cannot
handle the case of split files

using any other build system isn't supported and cmake is circular with
libarchive

also add pgo and lto for a noticable performance improvement

.cmake usage requires all the files to be present

this also includes the .cmake files, letting cmake projects find libzstd

missed this in !28751. technically this should have pkgrel bump but if
it passes CI it's probably fine, no need to waste users' bandwidth

armv6 memory access and strict aliasing and PIC are fixed upstream, -O2
should be only if -Os was set

Closes GH-9542

This is the same memcpy()-in-hot-path xxHash problem as described
in community/xxhash commit message.

The bug makes "zstd -1" or "zstd -t" ~15% slower on x86_64 though
higher levels (>= 9) are almost unaffected.

Other aport changes:
 - make sure zlib/lzma/lz4 support is not compiled in automatically
   (status quo, just make it explicit);
 - re-enable armv7 since it is certainly well-supported by upstream,
   was disabled by some script in the first place and should not be
   affected by "Bus error" (i.e. some alignment problem) mentioned in
   commit 2bae6690...
 - use faster and shorter "make check" (unlike extensive "make test")
   on arm* builders.
