build-system/gnu: Patch shebangs in all the source; patch SHELL in makefiles.
* guix/build/utils.scm (call-with-ascii-input-file): New procedure. (patch-shebang): Use it. (patch-makefile-SHELL): New procedure. * guix/build/gnu-build-system.scm (patch-source-shebangs): Patch all the files, not just executables; remove `po/Makefile.in.in' patching. (patch-generated-files): Rename to... (patch-generated-file-shebangs): ... this. Patch executables and makefiles. (%standard-phases): Adjust accordingly. * distro/packages/autotools.scm (libtool): Remove call to `patch-shebang'. * distro/packages/base.scm (gcc-4.7): Likewise. (guile-final): Remove hack to skip `test-command-line-encoding2'. * distro/packages/bash.scm (bash): Remove `pre-configure-phase'. * distro/packages/readline.scm (readline): Likewise. * distro/packages/ncurses.scm (ncurses): Remove `pre-install-phase'.
