OvmfPkg: Work around issue seen with kvm + grub2 (efi)
When OVMF is run with kvm and grub2 (efi), an exception
occurs when mmx/sse registers are accessed.
As a work around, this change eliminates firmware usage
of these register types.
First, only the BaseMemoryLib implementation
MdePkg/Library/BaseMemoryLibRepStr/BaseMemoryLibRepStr.inf
is used.
Second, the GCC compiler is passes the additional
'-mno-mmx -mno-sse' parameters.
