Yes, it is part of the qemu package.

I wonder why it must be compiled unconditionally.
This is my workaround:

sed -i 's@EFIROM@KAPUTT@g' roms/Makefile
efirom=
test -x "$(type -P EfiRom)" && KAPUTT="$_" efirom=efirom
make -C roms ${efirom} KAPUTT=${KAPUTT}

It is in ovmf-tools.rpm, which comes from ovmf. And looking at this package,
they also had to workaround the fact that edk2 does not cope with PIE.
