### `gn clean` the FUCHSIA_BUILD_DIR

## If FUCHSIA_BUILD_DIR is out/x64, this is simply:
##   gn clean out/x64
## It is useful to clean the build directory without having to re-gen.

"${FUCHSIA_DIR}/buildtools/gn" clean "$FUCHSIA_BUILD_DIR"

# Also clean zircon, it's not yet gn-ized, but we shouldn't care.
# "fx build-zircon -c" interprets "clean" as rm -rf $ZIRCON_BUILDROOT,
# so we do too.
