Debian:

$ apt-file search libhandle
....
xfslibs-dev: /lib/libhandle.a
xfslibs-dev: /lib/libhandle.so
xfslibs-dev: /usr/lib/libhandle.a
xfslibs-dev: /usr/lib/libhandle.la
xfsprogs: /lib/libhandle.so.1
xfsprogs: /lib/libhandle.so.1.0.3
$

So the libhandle library DSO is shipped in xfsprogs. The /static/
library is shipped in xfslibs-dev.

So what is fstests requiring here - the DSO or the static library?
If it's the static library, then why does it need that and why can't
it use the DSO shipped as part of the main xfsprogs package?

Only if it requires the static libhandle.a library.

But that said, we should probably get rid of the static library and
just ship the DSO - I can't think of a good reason for shipping a
static version of a DSO in a "dev" package these days.
