Hi,

When build ovmf with the latest two commits of master branch, we meet error on Red Hat 7.6 with gcc version 4.8.5, but succeed on Red Hat 8.0 with gcc version 8.2.1.

Steps:
git clone https://github.com/tianocore/edk2.git
cd edk2
git submodule init
git submodule update -recursive
OvmfPkg/build.sh -a X64 -n 64

Error log:
