The problem is that without # this, ccache would link against the zlib of the build system, but we # might build and install a different version of zlib in $(O)/host # afterwards, which ccache will pick up. This might break if there is # a version mismatch. A solution would be to add host-zlib has a # dependency of ccache, but it would require tuning the zlib .mk file # to use HOSTCC_NOCCACHE as the compiler. Instead, we take the easy # path: tell ccache to use its internal copy of zlib, so that ccache # has zero dependency besides the C library.
