Makefile variables not working as expected

I am trying to compile a program using this makefile:

GCCPARAMS = -m32 -fno-use-cxa-atexit -nostdlib -fno-builtin -fno-rtti -fno-exceptions -fno-leading-underscoreASPARAMS = --32objects = src/loader.o src/kernel.o%.o: src/%.cpp    gcc $(GCCPARAMS) -c -o $@ $<%.o: src/%.s    echo $(ASPARAMS)    as $(ASPARAMS) -o $@ $<kernel.bin: linker.ld $(objects)    ld $(LDPARAMS) -T $< -o $@ $(objects)install: kernel.bin    sudo cp $< boot/mykernel.bin

The problem comes when doing make which prints the following:

as   -o src/loader.o src/loader.ssrc/loader.s: Assembler messages:src/loader.s: Warning: end of file not at end of a line; newline insertedsrc/loader.s:18: Error: operand type mismatch for `push'src/loader.s:19: Error: operand type mismatch for `push'make: *** [<builtin>: src/loader.o] Error 1

As you can se the variable is not properly set, instead, make puts a space where the variable should be. That causes the assembler compiler to think it's a 64 bit architecture and giving some errors.

Any idea of what is going on? I am doing this using WSL2 by the way.
