issue: 3875155 Fix cppcheck skipping files from scanning

[pasis]

Description

cppcheck skips most of the files from scanning and returns successfully. This potentially hides issues that can be detected in CI.

Replace #error with #warning in the endianness check to allow cppcheck to find a working configuration.

#warning still fails the compilation process, so we won't miss a wrong endianness configuration.

What

Replace #error with #warning in the endianness check to allow cppcheck to find a working configuration.

Why ?

Fix cppcheck job in CI.
