SHA support on AMD Ryzen CPUs requires gcc version 5 or higher. Add one of the following to CFLAGS for SHA
support depending on your CPU and compiler version:
"-march=native" is usually the best choice and is used by build.sh
"-march=znver1" for Ryzen 1000 & 2000 series, znver2 for 3000.
"-msha" Add SHA to other tuning options

Static builds should only considered in a homogeneous HW and SW environment.
Local builds will always have the best performance and compatibility.

N is the number of threads for the compiler to use.
Some newer CPU architectures may not be defined for "-march=native" in older versions of gcc and can't be compiled using the default build script. It is often possible to compile an optimum build by manually specifying options.
Ryzen 3000 uses "-march=znver2" natively but znver1 also works.
Ryzen 5000 uses "-march=znver3" natively in gcc-11 and newer. For olders versions of gcc use "-march=znver2 -mvaes"
Ryzen 7000 uses "-march-znver4" but is not yet defined in gcc. It can be compiled with gcc-11 by using "-march=znver3 -mavx512f -mavx512dq -mavx512bw -mavx512vl"
Many examples for various CPU architectures can be found in file build-allarch.sh
