Thank you very much for your response.

I'm afraid I didn't understand (as I am new to yocto and try to understand it). Did you mean, the following statement in my-image.bb file generates the static apps which is not a good approach?
SDKIMAGE_FEATURES_append = " staticdev-pkgs"
I introduced this statement because I got linking errors when compiling/linking using the SDK complaining about missing libs just like ...
/opt/mydistro/1.0.0/sysroots/x86_64-pokysdk-linux/usr/libexec/arm-poky-linux-gnueabi/gcc/arm-poky-linux-gnueabi/8.3.0/real-ld: cannot find -lpthread
/opt/mydistro/1.0.0/sysroots/x86_64-pokysdk-linux/usr/libexec/arm-poky-linux-gnueabi/gcc/arm-poky-linux-gnueabi/8.3.0/real-ld: cannot find -ldl
/opt/mydistro/1.0.0/sysroots/x86_64-pokysdk-linux/usr/libexec/arm-poky-linux-gnueabi/gcc/arm-poky-linux-gnueabi/8.3.0/real-ld: cannot find -lstdc++
/opt/mydistro/1.0.0/sysroots/x86_64-pokysdk-linux/usr/libexec/arm-poky-linux-gnueabi/gcc/arm-poky-linux-gnueabi/8.3.0/real-ld: cannot find -lm
/opt/mydistro/1.0.0/sysroots/x86_64-pokysdk-linux/usr/libexec/arm-poky-linux-gnueabi/gcc/arm-poky-linux-gnueabi/8.3.0/real-ld: cannot find -lc
collect2: error: ld returned 1 exit status
makefile:128: recipe for target 'arm' failed
make: *** [arm] Error 1
When using this statement (SDKIMAGE_FEATURES_append = " staticdev-pkgs") I can see in /opt/mydistro/1.0.0/sysroots/usr/lib many *.a files which are not present without this statement. But I am not sure if this statement is correct? Maybe there is another approach for including the missing libs?
And what do you mean with "PIE related"? Are you thinking of an Raspberri PI?

Also I would like to verify, but do not know how to setup for aarch64 or mips. Can you provide a short example?
Thank you for your support.
