The qemu build is broken in some way. To fix it you have to do:
cp pc-bios/optionrom/linuxboot_dma.bin pc-bios/optionrom/

Re: [PATCH v2 0/7] tests/qemu: Add program for tracing and analyzing boot times.
I gave this series a spin, along a custom QEMU, and `supermin` from Git,
for my `libguestfs-test-tool` itself fails with:
"Could not open option rom 'linuxboot_dma.bin': No such file or
directory"
How I went about:
(1) Build QEMU with
https://lists.gnu.org/archive/html/qemu-devel/2016-01/msg05891.html
-- Add optionrom compatible with fw_cfg DMA version
Build QEMU with the above patch:

[PATCH v2 0/7] tests/qemu: Add program for tracing and analyzing boot times.
v1 was here:
https://www.redhat.com/archives/libguestfs/2016-March/thread.html#00157
Not running the 'hwclock' command reduces boot times considerably.
However I'm not sure if it is safe. See the question I posted on
qemu-devel:
http://thread.gmane.org/gmane.comp.emulators.qemu/402194
At the moment, about 50% of the time is consumed by SeaBIOS. Of this,
about ⅓rd is SGABIOS
