I think this line is not correct: you're accessing "location" varible inside 
"project" module, which is internal to that module, and generally speaking, 
has no relation to the Jamfile location.

I think they should be evaluated only one. If there are really evaluated twice 
for you, maybe you could send me a testcase?

The following code works for me:

local location = [ project.attribute $(__name__) location ] ;
local l = [ path.glob $(location) : *.c ] ;
ECHO $(l) !!! ;

This probably should become new rule "glob" available in Jamfile context...
