+# 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.

+#    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.
