That's correct.

The intent of this patch is to continue to use /lib/ld-linux.so.3[*] for
ARM EABI (aka "softfloat"/armel), but switch to
/lib/arm-linux-gnueabihf/ld-linux.so.3 for the hard float variant.
This allows for concurrent support of both ABIs on the same install.
/lib/ld-linux.so.2, as I understand it, is the legacy ABI (OABI). My
updated patch preserves this support.

[*] The /lib/ld-linux.so.3 bit isn't visible in my latest patch
because it is specified in a different file.
