 configure: Coerce gcc to use $LD instead of system default

 The configure script will now try to coerce gcc to use the linker
 pointed to by $LD instead of the system default (typically bfd ld).
 Moreover, we now check for `ld.gold` and `ld.lld` before trying `ld`.

 The previous behavior can be reverted to by using the new
 --disable-ld-override flag.

 On my machine gold seems to trigger an apparent infelicity in
 constructor behavior, causing T5435_asm to fail. I've opened #13883 to
 record this issue and have accepted the questionable constructor
 ordering for the time being.

 Test Plan: Validate with `config_args='--enable-ld-override'`
