+! No SIMD math functions are available for this platform.
Only in s390x/usr/include/: s390x-linux-gnu
Only in amd64/usr/include/: x86_64-linux-gnu
Not sure if the header should move to like libc6-dev-amd64|s390x packages, or
in arch specific subdirectory.
Also, slightly surpised that SIMD math functions are not available for
s390x, as we now target z13 minimum, and there should be SIMD
instructions available as built-ins.
Thus at the moment I cannot cross build s390x packages on amd64.
