Makefile remove files

For a schoolproject I try around with makefiles. First I create the files with 

install: main.c
    gcc -asve-temps main.c
    @if test ! -d bin/; then mkdir bin; else : fi
    mv a.out $(shell pwd)/bin/
    chmod 555 ./bin/a.out

Now I want to clear the project: 

clear:
@if test -d *.[osia]; then rm *.[osia] else : ; fi
@if test -d a.out then rm a.out; else: ; fi

Running make install works fine. Running make clear produces the error code: 

/bin/sh: 1: test: main.i: unexpected operator

and does not remove the requested files. I want to delete all the *.o *.s *.i and *.a files by running the make clear target using the pattern given above avoiding the error cannot remove ... : no such file or directory

test expects a single argument; when you pass it a glob, it's getting a bunch of them. Something like find will work in this case:

find . -maxdepth 1 -name '*.[osia]' -delete

Or, why check if the file exists at all?

rm -f *.[osia]

Couple of other notes: if you don't have an else clause in your if statement, don't include it. Read up on the test command; you certainly don't want to be using -d if you're looking for files. And, you can use the variable $PWD in place of running a subshell to get it.
