springbok: avoid warnings from the driver for unused flags
The CMake configuration forces `-D NDEBUG` and the GNU depfiles (unless
`CMAKE_FORCE_DEPFILES` is unset when the ASM language is enabled).
Rather than unsetting `CMAKE_FORCE_DEPFILES` before enabling the
language and filtering out the `-D NDEBUG` from the ASM flags, simply
rename the source files to `.S` which causes them to be processed as
ASM+CPP which avoids the warnings as the CPP will consume the macros and
the deps. This also makes it easier to modify the assembly routines to
behave differently with assertions.
