- Subject: [PATCH] ARM: Use different linker path for hardfloat ABI
This is an updated version of a patch Debian and Ubuntu are using to
use an alternate linker path for hardfloat binaries. The difference
with this one is that it covers the case where no float flag
was passed in, defaulting to the softfloat path.
