https://bugs.gentoo.org/484560 From 3eab2b7675fc7e2889cd69285a2a31980a4bf504 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Thu, 12 Sep 2013 00:29:40 -0400 Subject: [PATCH] trylink: only prefix libs with -l If our pkg-config queries pass back a flag like -pthread, the trylink script will expand that to -l-pthread. So change trylink to only add the -l prefix to a value that doesn't have a - prefix already.
