Hello EDK2 community,

I found out that it depends on the platform. I work with next changes:

I used the command build -a IA32 -a X64 -p UefiPayloadPkg/UefiPayloadPkg.dsc -b DEBUG -t GCC5 -Y COMPILE_INFO -y BuildReport.log for building edk2 for x86_64. Debuuging for this plarform WORKING!!! I attach log below.

The build for the x86 platform failed. I use command build -a IA32 -p UefiPayloadPkg/UefiPayloadPkg.dsc -b DEBUG -t GCC5 -Y COMPILE_INFO -y BuildReport.log . Result is:

I can't figure out why this is happening.
