[PATCH 2/3] BaseTools/Conf/tools_def: Fix CLANGDWARF_IA32_X64

["Patrick Rudolph" <patrick.rudolph@9elements.com>]

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.
