Little Richard made a stack (4)
I believe the answer is:
rick
This clue is a double definition.
'little richard' is the first definition.
'a stack' is the second definition.
(rick is a kind of stack)
'made' acts as a link.
(Other definitions for rick that I've seen before include "Sprain; hay pile" , "Wrench; haystack" , "result of making hay?" , "Stack, of hay say" , "Stack of hay - pain in the neck" .)
