    Require GCC 6.2 or later to build glibc.
    
    As discussed during development for glibc 2.29, when we increased the
    required minimum GCC version for building glibc to GCC 5, working
    purely based on the times at which such requirements have been
    increased in the past it would be appropriate for glibc 2.30 to
    require GCC 6 (matching GCC 4.9 having been required for glibc 2.26).
    Naming 6.2 specifically as the minimum version then means a separate
    version requirement no longer needs to be specified for powerpc64le.
    
    Thus, this patch increases the minimum to 6.2, removing the
    documentation of the separate requirement for powerpc64le.  It does
    not remove the powerpc64le configure test, or any __GNUC_PREREQ that
    could be removed as not being in installed headers or files shared
    with gnulib; I think such cleanups are best done separately.
    
    Tested for x86_64.
    
    	* configure.ac (libc_cv_compiler_ok): Require GCC 6.2 or later.
    	* configure: Regenerated.
    	* manual/install.texi (Tools for Compilation): Update minimum GCC
    	version.
    	* INSTALL: Regenerated.
