[Bug translator/10917] New: environment variable expansion in executable search

["foom at fuhm dot net" <sourceware-bugzilla at sourceware dot org>]

I'd like to be able to do:
probe process("$INSTALL/lib/libMyStuff.so").function("hello") {}

That is: in addition to doing $PATH finding for the process probe, I'd like it to first expand environment 
variables from the user (the one running stap)'s environment.

At first thought, I'd have $$ to escape a $, and also support "${ENVVARNAME}".

If you think this is a good idea, I should be able to come up with a patch to implement it.
