Subject: [PATCH] add qemu-wrapper support

V8's JIT infrastructure requires binaries such as mksnapshot and mkpeephole to
be run in the host during the build. However, these binaries must have the
same bit-width as the target (e.g. a x86_64 host targeting ARMv6 needs to
produce a 32-bit binary). To work around this issue, cross-compile the
binaries for the target and run them on the host with QEMU, much like
gobject-introspection.

However, for the host-variant we do not want to use a
qemu-wrapper, so add @MAYBE_WRAPPER@ to the needed files and sed the path to
the qemu-wrapper on target builds, and remove @MAYBE_WRAPPER@ entirely on
host-builds.
