CPP is invoked via $(CC) -E and CCACHE is set for CC right above, so that'd call ccache twice.

[U-Boot] [PATCH 1/2] common: Add CCACHE variable to allow use of ccache
Prefix HOSTCC and CC with CCACHE variable to allow easy use of ccache. In case the user wants to use ccache, exporting CCACHE=ccache will do the trick. It is of course possible to either make the cross-compiler name into a shellscript which invokes the ccache and the compiler, but setting this variable makes use of ccache easier and more convenient. Using ccache becomes convenient when using MAKEALL for large build tests, where the speedup after building the cache for the first time is about 4-6 times.
