While working on the Reproducible Builds effort [0], we noticed that qemu's documentation and manpages generates non-reproducible output, possibly based on which shell is set to /bin/sh and the handling of whitespace in the corresponding echo implementation[1]. I believe the attached patch should resolve this issue by removing trailing whitespace from two lines in the file used to generate the documentation, though I haven't confirmed for sure.

Subject: [PATCH] Remove trailing whitespace in qemu-options documentation, as
it causes reproducibility issues depending on the echo implementation used by
the Makefile.
