Details:
Consider this makefile:
v := two
%.bar: var := one
%.bar: var += $(v)
%.bar: var += three
v :=
%.bar: ; @echo $(var)
all: foo.bar
When used with 3.81, it prints 'one three' while I would expect it to print
'one two three'. If I change pattern-specific to target-specific assignment,
it works as expected:
foo.bar: var := one
foo.bar: var += $(v)
foo.bar: var += three
The workaround for this problem is to use temporary variable:
tmp := one
tmp += $(v)
tmp += three
%.bar: var := $(tmp)
