NASM version 2.14.01 supports all x86 ISA in this library. Since this version has been out since 2018, it is safe to only permit the library to be compiled with this minimum version, as announced in issue #297. Signed-off-by: Pablo de Lara <pablo.de.lara.guarch@intel.com>

ISA-L Build Details
Build tools
NASM: For x86-64 builds it is highly recommended to get an up-to-date version of nasm that can understand the latest instruction sets. Minimum version of NASM is 2.14.01, supporting all the ISA needed for the library. The configure or make tools can check for this minimum version.
checking for nasm... yes
checking for modern nasm... yes
If an appropriate nasm is not available from your distro, it is simple to build from source or download an executable from nasm.
git clone --depth=10 https://github.com/netwide-assembler/nasm
cd nasm
./autogen.sh
./configure
make
sudo make install
Windows Build Environment Details
The windows dynamic and static libraries can be built with the nmake tool on the windows command line when appropriate paths and tools are setup as follows.
Download nasm and put into path
Download and install nasm and add location to path.
set PATH=%PATH%;C:\Program Files\NASM
Setup compiler environment
Install compiler and run environment setup script.
Compilers for windows usually have a batch file to setup environment variables
for the command line called vcvarsall.bat or compilervars.bat or a link to
run these. For Visual Studio this may be as follows for Community edition.
C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvarsall.bat x64
For the Intel compiler the path is typically as follows where yyyy, x, zzz represent the version.
C:\Program Files (x86)\IntelSWTools\system_studio_for_windows_yyyy.x.zzz\compilers_and_libraries_yyyy\bin\compilervars.bat intel64
Build ISA-L libs and copy to appropriate place
Run nmake /f Makefile.nmake
This should build isa-l.dll, isa-l.lib and isa-l_static.lib. You may want to
copy the libs to a system directory in the dynamic linking path such as
C:\windows\system32 or to a project directory.
To build a simple program with a static library.
cl /Fe: test.exe test.c isa-l_static.lib
