 If that is the case, it will be an issue for the internal toolchain wrapper as
well, since it will just overwrite the .real...

 But of course, we don't have an internal toolchain for Blackfin anymore, so
I'll try to create an ARM FLAT toolchain and see how far I get...

 Doesn't look great but it would work.

 Another option is to move it to a subdirectory:
$(HOST_DIR)/usr/bin/toolchain-binaries or something like that.
