Debug builds are not wroking correctly

[MichalMrozek]

Hello,
@ruiling reports problem with debug build configuration:
intel/compute-runtime#26

Looks like problems while building IGC.
"EnableDxbcDump not defined but used in IGC/AdaptorCommon/customApi.cpp
an invalid product family was passed in to IGC::SetWorkaroundTable() which triggers an assert there.
please help to fix them."

Hi, Thanks for bring this to our attention. We have fixed this in our internal code and it will be mirrored after passing validation. Thank you.
