[Buildroot] [git commit] package/qemu: unset TARGET_DIR

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=138014bf233c1b946e7dab5a8cb56d4cae3093d7
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

qemu uses TARGET_DIR internally, and it is at least used to display the
shortened compiling commands, like (with a TARGET_DIR=/path/to/target):

    CC /path/to/targetblock/write-threshold.o

VS

    CC block/write-threshold.o

There does not seem to be any adverse effect to that, but this is very
confusing to see, especially when building the host variant.

Fix that by unsetting TARGET_DIR prior to building.
