[PATCH 3/3] doc-rst:c-domain: function-like macros index entry

[Markus Heiser <markus.heiser@xxxxxxxxxxx>]

From: Markus Heiser <markus.heiser@xxxxxxxxxxx>

For function-like macros, sphinx creates 'FOO (C function)' entries.
With this patch 'FOO (C macro)' are created for function-like macros,
which is the same for object-like macros.
