I have no problem with that, but looking at the logs, GNU Binutils >= 2.25 started to be required in June 2017, immediately before glibc release 2.26. That is commit 073e8fa7739e. Should glibc start to require a newer Binutils? For the record: GNU Binutils 2.25 was tagged in Dec. 2014 GNU Binutils 2.26 was tagged in Jan. 2016 It could also remove a test from sysdeps/arm/configure.ac. -- Tulio Magno
