Since commit 9f16f65705, build with asm
can fail on:
nasm -I../ASM/x86/ -Dx64 -f elf64 -o 7zCrcOpt_asm.o ../../lzma/ASM/x86/7zCrcOpt_asm.asm
CC LzmaEnc.lo
CC LzmaLib.lo
CC Alloc.lo
CC Threads.lo
cp 7zCrcOpt_asm.o .libs/
cp: cannot create regular file '.libs/': Not a directory
make[4]: *** [Makefile:678: 7zCrcOpt_asm.lo] Error 1
make[4]: *** Waiting for unfinished jobs....
So create .libs directory before copying 7zCrcOpt_asm.o
