Since we always have a toolchain wrapper now, we can move the ccache call to the toolchain wrapper. The hostcc ccache handling obviously stays. The global addition of ccache to TARGET_CC/CXX is removed, but many individual packages and infras still add it. This means we have a chain like this: ccache -> toolchain-wrapper -> ccache -> gcc However, this is fairly harmless: for cache misses, the inner ccache just adds overhead and for cache hits, the inner ccache is never called. Later patches will remove these redundant ccache calls. As a side effect, perl now supports ccache as well.
