calcs uses the compiler option -mpreferred-stack-boundary=4 to configure a stack alignment of 16 bytes. Clang uses the option -mstack-alignment instead, which expects as parameter the alignment in bytes, and not a power of two like -mpreferred-stack-boundary. Probe for both compiler options and use the correct one, similar to what is done in arch/x86/Makefile.
