Yuri Victorovich 679b9e2f43 Mk/bsd.ccache.mk: Add CCACHE_ENABLED variable for ports' convenience
Some projects do some special handling when the ccache program is present.
This causes problems because ports framework has its own ccache settings
and mere presence of ccache program doesn't mean that ccache is enabled.
The new CCACHE_ENABLED variable can be used to tell projects if ccache
is really enabled.

# User settable:
# - WITH_CCACHE_BUILD - enables depending on ccache and using it in the build.
# - CCACHE_PKG_PREFIX - where ccache is already installed. Default: LOCALBASE
# This should not be set unless it differs from the
# default.
# - CCACHE_DIR (optional) - where ccache stores its cache. See ccache(1).
# This should not be set unless it differs from the
# default.
#
# Port use (users should not modify these):
# - CCACHE_ENABLED - tells the port if ccache is enabled.
# - CCACHE_BIN - path to the ccache binary. Intended to be prefixed before CC.
# - CCACHE_WRAPPER_PATH - path to directory containing compiler symlinks back
# to ccache. For example, gcc5 -> ccache. Intended
# to be added to $PATH
# This is expected to end in /libexec/ccache.
#
# In general CCACHE_WRAPPER_PATH should be placed into the env PATH for a
# port build rather than directly invoking CCACHE_BIN. Then when the port
# runs 'cc' or 'gcc5' it will find the symlinks. If a port is directly
# using a full path to a specific compiler then CCACHE_BIN can possibly be
# prefixed in front of it, if the CC path cannot be fixed to be relative.
#
# Port use (special case):
# - NO_CCACHE - disable using ccache entirely. This is for when a port build
# fails with ccache being used. Typically this should be
# temporary only.
# - NO_CCACHE_DEPEND - avoid automatically depending on ccache but still
# attempt to use it in PATH. This is typically only
# needed in devel/ccache itself.
