Paths are stored by 'configure' - that could be where the problem is, if
the code is moved after running configure, or a path with symlinks is
supplied (so .. goes to the wrong place).
The top of my Makefile is:
  srcdir = .
  top_srcdir = .

'make' is designed only to be run from the top directory of the tree,
not subdirectories.

But your example makes no sense: there is nothing to do for
'device-mapper' in 'doc', and it works for me anyway, both with -C and
using the alternative internal 'dot' target directly.

$ make -C doc device-mapper
make: Entering directory `/d/LVM2/doc'
make: Nothing to be done for `device-mapper'.
make: Leaving directory `/d/LVM2/doc'

$ make doc.device-mapper
make -C doc device-mapper
make[1]: Entering directory `/d/LVM2/doc'
make[1]: Nothing to be done for `device-mapper'.
make[1]: Leaving directory `/d/LVM2/doc'
