+Subject: [PATCH] trylink: include LDFLAGS when checking linkage
+
+The user might be including options in their LDFLAGS (like -fuse-ld=gold)
+that change the behavior of the linker and thus change the results of the
+flag tests.  Make sure we include the user's LDFLAGS when running these
+tests so we filter out flags that will fail when used later on.
