For gcc-4.9, I always use automake-1.11.1 and autoconf-2.64
to regenerate 'configure' and 'Makefile.in' content.

The following are my steps:

1. Download automake-1.11.1 and autoconf-2.64 from:
  http://ftp.gnu.org/gnu/automake/
  http://ftp.gnu.org/gnu/autoconf/

2. Build them by your own:
(As usual, separating build folder and source folder is recommended.)

$ /path/to/src/automake-1.11.1/configure --prefix=/path/to/local
$ make
$ make install

$ /path/to/src/automake-2.64/configure --prefix=/path/to/local
$ make
$ make install

3. Suppose you have modified libgo/configure.ac and libgo/Makefile.am.
After you 'cd gcc-4.9.0/libgo/', you can use:

(To simply generate configure from a modified configure.ac)
$ PATH=/path/to/local/bin:$PATH autoconf

(To simply generate Makefile.in from a modified Makefile.am)
$ PATH=/path/to/local/bin:$PATH automake

(To generate both configure and Makefile.in)
$ PATH=/path/to/local/bin:$PATH autoreconf

Hope it helps.
