[Skiboot] [PATCH 2/2] test/hello_world: Fix makefile rule

[Joel Stanley]

 powerpc-linux-gnu-gcc -m64 -c -MMD -Itest/hello_world/hello_kernel/ -o
   test/hello_world/hello_kernel/hello_kernel.o
   test/hello_world/hello_kernel/hello_kernel.S
   test/hello_world/hello_kernel/asm-utils.h
 powerpc-linux-gnu-gcc: fatal error: cannot specify -o with -c, -S or -E
   with multiple files

GCC barfed as we were passing the header and the c file while compiling
with -c. Fix the rule to just build source file.
