[Buildroot] [git commit master 1/1] crosstool-ng: don't remove installation directory before installing

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=82cf0e93f1a72bb4af5b6e3c30f80b2e01bf2358
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

crosstool-ng would normally delete its installation directory before
installing the toolchain to ensure it wouldn't get confused by an earlier
build. Now that we're installing directly into HOST_DIR/usr, this doesn't
work very well - So get rid of the rm's.

+ct-ng: don't remove CT_PREFIX_DIR
+
+You might want to install the ct-ng toolchain into an existing directory
+with other files (which is what we're doing in BR for HOST_DIR/usr),
+so don't remove it.
