Here's the problematic Makefile:
CFLAGS += -std=c11
CFLAGS += -fPIC
CFLAGS += -Wall
CFLAGS += -Wextra
CFLAGS += -Werror
CFLAGS += -Wwrite-strings
CFLAGS += -Wno-unused-variable
CFLAGS += -Wno-parentheses
CFLAGS += -Wpedantic
CFLAGS += -Warray-bounds
CFLAGS += -Wno-unused-function
CFLAGS += -Wstrict-prototypes
CFLAGS += -Wdeprecated
CFLAGS += $(EXTRA_CFLAGS)
TARGET := arena
TEST_TARGET := tests
SLIB_TARGET := libarena.a
DLIB_TARGET := libarena.so
RM := /bin/rm -f
static: $(SLIB_TARGET)
$(SLIB_TARGET): $(TARGET).o
$(AR) rcs $@ $(TARGET).o
shared: $(DLIB_TARGET)
$(DLIB_TARGET): $(TARGET).o
$(CC) $(CFLAGS) $(TARGET).o -o $@ $(LDFLAGS) -shared
test:
$(MAKE) EXTRA_CFLAGS="-DDEBUG" $(TEST_TARGET)
./$(TEST_TARGET) --verbose=3
clean:
$(RM) $(TEST_TARGET) $(TARGET).o $(SLIB_TARGET) $(DLIB_TARGET)
.PHONY: release debug static shared test clean

which results in:

There are multiple duplicates to this question, but they all suggest using gmake instead of make. And whilst that works, I do not wish to use gmake.
Here's the man page for make for Solaris: make
Running with:
make -x SUN_MAKE_COMPAT_MODE=GNU test
outputs the same.
Changing all assignments of the form := to = solves the problem.
Solaris make documentation defines := as a "conditional macro assignment", whilst the documentation for GNU make defines it as a "Simply Expanded Variable Assignment".
