some configure.in cleanups.  In particular, I replaced all echos with
  AC_MSG_... macros.
The gcc version (for disabling dynamic code) is now checked in configure (not
  when compiling main.c)
updated elisp-comp install-sh missing mkinstalldirs from autoconf-2.54

   22: # This script is compatible with the BSD install script, but was written
