[OE-core] [PATCH 10/22] ovmf: Fix build with toolchain defaulting to PIE

GCC44_IA32_X64_DLINK_COMMON and GCC49_IA32_X64_DLINK_COMMON
variables add to final linker flags that ovmf build forms
on its own, so trying to inject it from environment will not
work.
Here we add option to disable pie during linking, which should
have been accompanied with correcponding gcc/cflags.
