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

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