Subject: trace: ensure .stp files are rebuilt if trace tool source changes
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ed8650586fed350e46a39d39eacec02a7f7ecc08;p=qemu.git

trace: ensure .stp files are rebuilt if trace tool source changes

The make rules for generating the .stp files forgot to add a dep
on $(tracetool-y) to trigger a rebuild if the trace tool source
changes.
