This patch implements a requirement of binutils >= 2.25 (up from 2.22) to build glibc. Tests for 2.24 or later on x86_64 and s390 are removed. It was already the case, as indicated by buildbot results, that 2.24 was too old for building tests for 32-bit x86 (produced internal linker errors linking elf/tst-gnu2-tls1mod.so). I don't know if any configure tests for binutils features are obsolete given the increased version requirement. Tested for x86_64. * configure.ac (AS): Require binutils 2.25 or later. (LD): Likewise. * configure: Regenerated. * sysdeps/s390/configure.ac (AS): Remove version check. * sysdeps/s390/configure: Regenerated. * sysdeps/x86_64/configure.ac (AS): Remove version check. * sysdeps/x86_64/configure: Regenerated. * manual/install.texi (Tools for Compilation): Document requirement for binutils 2.25 or later. * INSTALL: Regenerated.
