Andreas Rheinhardt ba94177242 avcodec/x86/Makefile: Only compile ASM init files when X86ASM is enabled
To do so, simply add these init files to X86ASM-OBJS instead of OBJS
in the Makefile. The former is already used for the actual assembly
files, but using them for the C init files just works, because the build
system uses file extensions to derive whether it is a C or a NASM file.

This avoids compiling unused function stubs and also reduces our
reliance on DCE: We don't add %if checks to the asm files except
for AVX, AVX2, FMA3, FMA4, XOP and AVX512, so all the MMX-SSE4
functions will be available. It also allows to remove HAVE_X86ASM checks
in these init files.
