To some extent variables in bmake (and other makes too) 
work like expressions in lazy programming languages (Haskell, Clean,
Lazy Lisp etc.). That is they "evaluated" only in special cases:
- in rules (${target} : ${dependeny}) during scaning Makefiles
- on the left side of =, != and +=
- on the right side of += and :=
- in conditions in .if operator
- ...

So, yes, you cannot right a=${a}.
Maybe := will satisfy your needs.
