macOS compilation

[paulotex]

Minimal changes for macOS:

• We need g++ from brew, I could not make the XCode accept the pthread syntax. After installing g++ with brew, edit linux_src_bin and use that instead of the default g++.
  • nasm needs -fmacho64 instead of -felf64
  • nasm needs --prefix _

I also added a "clean:" rule.

CC = /usr/local/opt/gcc/bin/g++-10

phenom2_benchmark: main.cpp asm.o
    $(CC) main.cpp asm.o -lpthread -ffast-math -msse3 -O3 -o phenom2_benchmark

asm.o: asm.asm AND_REG_REG.asm CMOVcc_REG_REG.asm PADDB_MMX.asm ADD_REG_1.asm SHR_REG_CL.asm AVXChecker.asm FLOPS.asm IMUL_REG_REG.asm
    nasm asm.asm -fmacho64 --prefix _ -o asm.o

clean:
    rm -f *.o phenom2_benchmark

Even better, thanks to nervosolek (pull requests), "-std=c++11" is enough to use XCode. So the changes are simply: -fmacho64 --prefix _ for nasm.
