build wrong for undefined reference to `__rdtsc'

[bollwarm]

I installed in centos 6.5 clang-3.4.2-4.el6.x86_64, there is wrong:

i am also having the same issue trying to compile it on a Redhat Linux Server

[SgtTheDarknezz]

confirmed having the same issue.

roll back to version 1.0.3 for now https://github.com/robertdavidgraham/masscan/archive/1.0.3.tar.gz

nice

I was able to overcome this problem on CentOS 7 by changing the compiler from clang to gcc in the Makefile.

From:

#use llvm by default, GNU C otherwise
CC=clang

To:

#use llvm by default, GNU C otherwise
CC=gcc

Hope this helps anyone with this issue!
