编译nasm(2.16.01)

压缩包
可以选择在/etc/yum.repos.d下新增nasm.repo，从而用yum 安装

[nasm]
name=The Netwide Assembler
baseurl=http://www.nasm.us/pub/nasm/stable/linux/
enabled=1
gpgcheck=0

[nasm-testing]
name=The Netwide Assembler (release candidate builds)
baseurl=http://www.nasm.us/pub/nasm/testing/linux/
enabled=0
gpgcheck=0

[nasm-snapshot]
name=The Netwide Assembler (daily snapshot builds)
baseurl=http://www.nasm.us/pub/nasm/snapshots/latest/linux/
enabled=0
gpgcheck=0

由于最新版本的nasm需要更新glibc，选择用2.16.01

wget https://www.nasm.us/pub/nasm/releasebuilds/2.16.01/nasm-2.16.01.tar.gz
