I've got this in make.conf, which gets me part-way there:

CMAKE_COLOR_MAKEFILE=OFF
NOCOLOR="true"
GCC_COLORS=""

I've also got this in /usr/local/bin/rustc and symlinked to 
/usr/local/bin/cargo:

----/usr/local/bin/rustc:----#!/usr/bin/perlmy @newargs=();my $skipnext=0;my $me=$0;$me =~ 
s(.*\/)();push @newargs, "--color";push @newargs, "never";foreach $arg 
(@ARGV) {    if($arg eq "--color"){    $skipnext =1;    } 
elsif($skipnext == 1){    $skipnext = 0;    } else { # any arg EXCEPT 
color gets passed along verbatim     push @newargs, $arg    
}}exec("/usr/bin/${me}",@newargs);

This last trick could probably be used for other commands as well 
(modulo specific argument)
