This issue is just fixed in GCC main trunk. I tried below latest GCC trunk
version and it can pass build the edk2 with GCC5 toolset. FYI.
Thanks!

Hi Cran,
This issue might be a GCC6 LTO regression bug, and I've filed a bug to GCC
community as below. Please don't use the GCC6 with edk2 GCC5
Hi Cran,
This issue might be a GCC6 LTO regression bug, and I've filed a bug to GCC
community as below. Please don't use the GCC6 with edk2 GCC5 toolchain for now,
the GCC5 (gcc-5) should works.

I build OVMF GCC X64 image, can boot Qemu into shell with below commands. I can
enter shell, reconnect -r, exit to setup, and the vga display looks good to me.
What build command did you use?
build -t GCC5 -a X64 -p OvmfPkg/OvmfPkgX64.dsc -n 5 -b

IA32 or X64? I noticed that EmulatorPkg-X64 just produces a segfault
when booting. IA32 works just fine. I didn't try to use GCC49 yet.
X64 - both DEBUG and RELEASE.

I just tried building OVMF from git tip with the GCC5 toolset and the
emulated vga display never got initialized. Rebuilding with GCC49 worked.
