Just to confirm, do you have all of these in /usr/lib64?

$ ls -l /usr/lib64/libnuma*
lrwxrwxrwx. 1 root root 16 Nov 4 19:00 /usr/lib64/libnuma.so -> libnuma.so.1.0.0
lrwxrwxrwx. 1 root root 16 Nov 4 19:00 /usr/lib64/libnuma.so.1 -> libnuma.so.1.0.0
-rwxr-xr-x. 1 root root 62424 Nov 4 19:00 /usr/lib64/libnuma.so.1.0.0

As of HEAD, line 957 of meson.build is

if not cc.has_header('numa.h', dependencies: libnuma, required: libnumaopt)

I'm not familiar at all with meson, but I wonder exactly what the
dependencies: bit does. That kind of looks like it might cause the
check to fail if the libnuma library isn't there, which is something
we do need to check, but doing it this way seems like it'd produce
a pretty misleading failure message if numa.h exists but the library
doesn't.
