<literal>cc-wrapper</literal>'s setup-hook now exports a number of
environment variables corresponding to binutils binaries,
(e.g. <envar>LD</envar>, <envar>STRIP</envar>, <envar>RANLIB</envar>,
etc). This is done to prevent packages' build systems guessing, which is
harder to predict, especially when cross-compiling. However, some packages
have broken due to this—their build systems either not supporting, or
claiming to support without adequate testing, taking such environment
variables as parameters.
