All of them for proctical purposes.

xz libs come under lzma name.

$ rpm -ql xz-devel | grep lib
/usr/lib64/liblzma.la
/usr/lib64/liblzma.so
/usr/lib64/pkgconfig/liblzma.pc

$ rpm -q kmod --requires|grep -c lzma
2

Kmod is properly linked wuth xz/lzma:

BuildRequires:▸ xz-devel >= 1:4.99

$ ldd /sbin/kmod 
	linux-vdso.so.1 (0x00007fffc03de000)
	liblzma.so.5 => /lib64/liblzma.so.5 (0x00007fc2271b1000)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
	libz.so.1 => /lib64/libz.so.1 (0x00000038b0800000)
	libpthread.so.0 => /lib64/libpthread.so.0 (0x00007fc226f94000)
	libc.so.6 => /lib64/libc.so.6 (0x00007fc226bed000)
	/lib64/ld-linux-x86-64.so.2 (0x00007fc2273d7000)

Thanks for fixing stripping/compression issue.
