new e40ba04a libtool: Check if -no-canonical-prefixes supported
e40ba04a is described below
commit e40ba04af725eb49db6d61471a4804efe682e423

libtool: Check if -no-canonical-prefixes supported
The compiler fails with the -no-canonical-prefixes flag in certain
environments. Check if the flag is supported in the current environment
and skip the test if it is not supported.
* tests/bug_62343.at: Skip test if -no-canonical-prefixes is unsupported
in the current environment.
