This was change needed to move forward with ACVP testing on powerpc64
for NetOS.
Our ACVP tool was not working properly on the PowerPC Big Endian
platform that NetOS needs to support. go1.21 has support for
`binary.NativeEndian`, but we can't use the newer version yet. This uses
a workaround with `unsafe.Pointer` until we can upgrade.
This is harder to test, but it might be doable by recompiling the cross
compilation tool chain we have with gccgo enabled. It's harder to
branch out the logic within the script to account for the different
behavior though, might do so in a follow up PR.
Works on the powerpc host NetOS lent us. Built with `gccgo` from gcc-12
with a powerpc64 cross compilation toolchain:
```
CC=powerpc64-unknown-linux-gnu-gcc \
GCCGO=powerpc64-unknown-linux-gnu-gccgo \
CGO_ENABLED=1 \
GOOS=linux \
GOARCH=ppc64 \
go build -compiler gccgo \
-gccgoflags '-static -mcpu=e6500' \
-o acvptool
```
