Build error

[preda]

I tried a build an it fails as below:

/home/preda/Common/Src/AMDTOSWrappers/src/common/osCpuid.cpp: In constructor 'osCpuid::osCpuid()':

Though I, too, can not build rcp, I was able to get past this by removing -Werror from Build/Linux/CXL_init.py.

This should now be fixed. You should now be able to build RCP with gcc7. You'll need to make sure you have the latest sources from the common-src-AMDTOSWrappers repo as well (running Scripts/UpdateCommon.py should get the latest changes from there)
