Ok. Was easy to work-around by wrapping bjam in a Perl script, though:

<script name="mybjam.pl">
#!/usr/bin/perl -w
$ENV{"GREETING"} = `echo Hello, world!`;
chomp($ENV{"GREETING"});
system("bjam", @ARGV);
</script>

I'm guessing it would be equally easy using Python, so maybe a shell function
could be added if/when BB is rewritten on top of Scons/Python.
