  Yes, sounds like a valid use case.

  I also expect that the LDFLAGS are not passed reliably for all packages:
they are hardly ever used, and there are no autobuilder configurations with
any LDFLAGS, so errors in passing LDFLAGS can go unnoticed.

  I don't think we have any other architecture currently in buildroot that
requires something to be passed to ld. If this wrapper construction is
added to buildroot, it would be good if we would also have an internal
use case.
