| # Force ccache to use its internal zlib. 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. |

| # Patch host-ccache as follows: |
| # - Use BR_CACHE_DIR instead of CCACHE_DIR, because CCACHE_DIR |
| # is already used by autotargets for the ccache package. |
| # BR_CACHE_DIR is exported by Makefile based on config option |
| # BR2_CCACHE_DIR. |
| # - Change hard-coded last-ditch default to match path in .config, to avoid |
| # the need to specify BR_CACHE_DIR when invoking ccache directly. |
