[Daniele E. Domenichelli]

Hello,

Please review topic fix_link-line-dedup_regression:


Fix regression in link order introduced by the link-line-dedup topic

Some compilers will fail linking if an executable is linking to a
library that is not used and a static library that uses the shared one.

This patch reverse the direction of the for loop that removes the
duplicate shared libraries, in order to ensure that the last occurrence
of the library is left instead of the first one.

Also adds one unit test to show the issue.


Cheers,
 Daniele
