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.
