remove these flags for crossdev:
> Manual CFLAGS:   -march=native -mtune=skylake  -O2             -pipe

You can do this with something like --lenv 'CFLAGS="-O2 -pipe"\nCXXFLAGS="-O2 -pipe" as part of the crossdev call.

Can you clarify what was your setup?

Is it a fresh crossdev run or an attempt to update old setup? For some reason host native compiler is used for target libraries instead of cross-compiler.
