* configure: Regenerated. * manual/install.texi (Tools for Compilation): Say 3.2 is required. (Configuring and compiling): Don't mention older GCC versions any more. * INSTALL: Regenerated. * manual/install.texi (Configuring and compiling, Installation, Running make install, Linux): Linux -> GNU/Linux where appropriate. * elf/rtld.c (_dl_start_final): Move defn before _dl_start so it can be inlined. Declare it with always_inline if [DONT_USE_BOOTSTRAP_MAP] and with noinline otherwise. Remove hack alloca use to prevent inlining, we can ask for it explicitly nowadays.
