You would have to define these values in the emulation parameters file
and then rebuild the linker,  but I think that in theory it should work.
This patch might do the trick, although I have not actually tested it
myself:

diff --git a/ld/emulparams/armelf.sh b/ld/emulparams/armelf.sh
index 1995c449975..5eba388fd81 100644
--- a/ld/emulparams/armelf.sh
