Drop the "-z max-page-size=0x40" option as it causes the ELF header to overflow into the .text section, causing undefined behaviour.
With high optimization level it corrupts essential code and the binary would crash. It might work with low optimization level though. As the default is to use Oz and LTO, it always crashes. Test: The ELF generated by 'python UefiPayloadPkg/UniversalPayloadBuild.py -a IA32' boots.
