Author: dim Date: Tue Dec 2 01:30:53 2014 New Revision: 275386 URL: https://svnweb.freebsd.org/changeset/base/275386
Log: Let GNU ld be less obscure about missing symbols and DSOs. If the BFD object looks like a typical shared library, suggest adding '-l<foo>', where <foo> has the 'lib' prefix and '.so<bar>' or '.a' suffix removed. Otherwise, suggest adding '-l:<foo>', where <foo> is the full DT_SONAME.
