Commit 7b93fadf3a38d1ed65ea5536a52efc2772c6e3b8 "Add basic version
of bridge helper" put the bridge helper executable into a fixed
${prefix}/libexec/ location, instead of using ${libexecdir} for
this.  At the same time, --libexecdir is being happily ignored
by ./configure.  Even more, the same patch sets unused $libexecdir
variable in the generated config-host.mak, and uses fixed string
(\${prefix}/libexecdir) for the bridge helper binary.

Fix this braindamage by introducing $libexecdir variable, using
it for the bridge helper binary, and recognizing --libexecdir.

This patch is applicable to stable-1.1.

I noticed the lack of this and just passed libexecdir= to make as a
workaround for our openSUSE package.

Thank you for your review.  However, passing libexecdir= to make
wont work, due to this:

configure:
echo "CONFIG_QEMU_HELPERDIR=\"$prefix/libexec\"" >> $config_host_mak

You need to pass CONFIG_QEMU_HELPERDIR= not libexecdir= to make.

Trust me, it does. Otherwise our package build would still fail since
our %_libexecdir is /usr/lib.

See Makefile, that one actually uses $(libexecdir):

Makefile:       $(INSTALL_DIR) "$(DESTDIR)$(libexecdir)"
Makefile:       $(INSTALL_PROG) $(STRIP_OPT) $(HELPERS-y)
"$(DESTDIR)$(libexecdir)"

Yes, it is a mess. :)

Makefile installs stuff to /usr/lib, but does the resulting
qemu binary look there too?

Bo Yang, I believe you tested the new bridge helper recently. Did you
run into any path issues with /usr/libexec vs. /usr/lib?

Bruce seems to use make install libexecdir=%_libexecdir for the kvm
package just like I do for qemu.

$ strings x86_64-softmmu/qemu-system-x86-64 | grep bridge

is a very simple test.  But I wonder if it is actually used
except of the help text?  It appears to be used, and even
enabled by default..  But I haven't looked into the code
this time, -EDEEPNIGHTALREADY :)

I had just copied what you had in your spec file wrt libexecdir ;)

But it does appear we have a problem with the path to the bridge helper in our
v1.1 rc3 based packages.

I didn't install the package. I only build and test the functions.

From the source code of configure, the CONFIG_QEMU_HELPERDIR is
hardcoded to $prefix/libexec. The patch seems ok to make
CONFIG_QEMU_HELPERDIR configurable.

Ping! This patch still seems missing in master and is needed for v1.1
and v1.2 packaging.

Ping^2! Could someone please apply this before it's too late?
