There hasn't been a --without-fp configure option since commit 
8df5d34720dd71e934545bade879e04697830757, so this commit message is 
clearly wrong.

Based on disassembling a 2.27 binary (2.27 being the first release after 
the sysdeps/ieee754/soft-fp directory was added), the sysdeps ordering was 
working then, but I confirm it's broken now.  Thus this raises the 
question of when the ordering broke, and thus (a) whether it might have 
broken for any other configurations using sysdeps/ieee754/soft-fp at the 
same time, and thus need fixing for them, (b) whether the breakage broke 
ordering for anything other than nofpu directories and (c) whether it 
might need a bug filed in Bugzilla if the issue was present in a release.  
The addition of /le sysdeps directories is one change that might have had 
a risk of breaking such ordering, but I don't know if it was that or not.
