Prior to the introduction of LDFLAGS_u-boot, was LDFLAGS not what was
used?  So before, anything that board/cpu code adds directly to LDFLAGS
(maybe they're supposed to use PLATFORM_LDFLAGS, but not all do) was
used in the final link.  After 8aba9dc, only things in
PLATFORM_LDFLAGS plus -Bstatic and -T are used in the final link.
