Remove ability to override $LD.

Since autoconf always uses $CC to link C programs, allowing users to
override LD caused mismatches between what LD_LINK_IFELSE thought worked
and what ld thought worked.  If you do need to do this kind of thing you
need to set a compiler flag such as gcc's -fuse-ld in LDFLAGS.
