Given that the value of 3 for Tag_ABI_HardFP_use is deprecated, that would
be reasonable.

Fair enough.  The thing that worries me is that the problematic file - crti.o -
comes from glibc and is going to affect the building of a lot of projects.  So
whilst glibc can be fixed, that will take some time, and in the meantime other
peoples projects are stuck.  A solution which will allow builds to complete -
even if it means ignoring a warning message from the linker, is probably
preferable to triggering an assert.
