selftests/x86: Add <test_name>{,_32,_64} targets
One can only use `make all` or `make <test_name>_<bitness>`
as make targets.
`make <test_name>` doesn't work as Ingo noticed:
x86> make test_vsyscall
gcc -O2 -g -std=gnu99 -pthread -Wall -no-pie test_vsyscall.c -o test_vsyscall
/tmp/aBaoo3nb.o: In function `init_vdso':
test_vsyscall.c:68: undefined reference to `dlopen'

test_vsyscall.c:88: undefined reference to `dlsym'

collect2: error: ld returned 1 exit status
<builtin>: recipe for target 'test_vsyscall' failed
make: *** [test_vsyscall] Error 1
Makefile target substitution neither works :-/
Generate .PHONY targets per-test and fix target substitution.
