Conditional Properties and Relative Paths

Here is another bug associated with Conditional Properties. In this
case, a relative path from a sub-project is handled correctly for an
<include> property, but not if the <include> property is Conditional.

Here we have an exe "hello" (exe/Jamfile) depending on a lib "mylib"
from a different project (lib/mylib/Jamfile).

Target "mylib" requires two include paths, "../include/foo" and
"../include/bar", relative to the "mylib" project. The only
difference between the two include paths is that "../include/bar" is
Conditional and "../include/foo" is not (see lib/mylib/Jamfile).

When "mylib.o" is built from the "hello" project, the include path for
"foo" gets converted properly to its relative path from the "hello"
project. But the include path for "bar" does NOT!

The bjam output below is from running bjam in the "exe" directory.
Note that in the g++ command line, the "foo" path is properly
converted to "../lib/include/foo" (CORRECT) but the "bar" path remains
"../include" (WRONG!).
