Yes and no. They're not quite the same thing -- we setup libtool to
compile things in the desired mode(s), but libtool isn't really ready
until configure completes.

Brian and Ralf are the experts here...

I'm guessing you had to specify --with-libnuma to find the library in
the first place...? If so, just don't specify it; if libnuma is not in
a standard location that is already searched by -L, then you'll have no
problem (i.e., the libnuma component's configure will fail and it will
automatically disqualify itself).

If, however, it does still find libnuma, you can specify
