>## www/chromium Makefile.local [contrib]

>##
>## Synopsis: Using a simple _WRAP_TOOL handling - lazily analogous onto 
>## pkgsrc cwrappers - for local cc, c++ cmds. These would match cmds under 
>## base system pathanmes. In each being provided via CC and CXX, these cmds
>## may furthermore be locally configured to use ccache. As such, these 
>## cmds may not easily be provided with a modification onto BINARY_ALIAS 
>##
>## Otherwise, using BINARY_ALIAS for defining generic toolchain cmds.
>##
>##
>## Rationale: Ensure that the toolchain variables configured in the build
>## environment will be used to provide any generic toolchain cmds used in
>## the build
>##
>## A more specific rationale: Ensure that ccache will be used, throughout 
>## the build, when CC and/or CXX represents a ccache wrapper
>##
>## Possible side effects: May serve to ensure a libtool-like configuration
>## for build
>##
>##
>## Assumptions
>##
>## - RM => rm -f
>##
>## - This cannot not be used when building ports-mgmt/pkg, if without
>##   modification, due to an early binding of BINARY_LINKDIR in this file
>##
>##
>## Further remarks
>##
>## - A similar build configuration may be of use when building the ports
>##   devel/chromium-gn, www/qt5-webtools (if using GN for chromium), ...
>##
>## - This does not provide any modification onto GN_ARGS such as
>##   for quoted GN cc, cxx, ld, nm, ar, and possibly readelf args. 
>##   Those arguments may not appear to be used in most of the build, 
>##   but may be provided to gn regardless.
