From: Alexander Bulekov <alxndr@bu.edu>
The fuzzers are built into a binary (e.g. qemu-fuzz-i386). To select the
device to fuzz/fuzz target, we usually use the --fuzz-target= argument.
This commit allows the fuzz-target to be specified using the name of the
executable. If the executable name ends with -target-FUZZ_TARGET, then
we select the fuzz target based on this name, rather than the
--fuzz-target argument. This is useful for systems such as oss-fuzz
where we don't have control of the arguments passed to the fuzzer.
[Fixed incorrect indentation.

Hi; this pullreq seems to include a stray change to the slirp
submodule in the "fuzz: select fuzz target using executable name"
commit. Could you fix that and resend, please?
(You might like to include a molly-guard in your pullreq
creation scripts; on my end I catch this sort of thing
when applying with a test like
if git diff master..staging | grep -q 'Subproject commit'; then
# complain and exit unless I used an explicit command
# line option to say I intended to include a submodule update
fi
though I haven't yet put the same test in the script I use
to send pullreqs, for some reason. I guess my workflow now
means I don't tend to accidentally commit submodule changes.)
thanks
