packages: Mark the `arguments' field of <package> as thunked.

* guix/packages.scm (<package>): Mark `arguments' as thunked.
  (package-derivation): Adjust accordingly.  Parameterize
  %CURRENT-SYSTEM to SYSTEM, so that arguments can refer to it.

* guix/build-system/gnu.scm (package-with-explicit-inputs): Expect
  `package-arguments' to always return a list, and return a list.
  (package-with-extra-configure-variable): Likewise.
  (static-package): Likewise.
* gnu/packages/base.scm (patch, findutils, gcc-4.7, binutils-boot0,
  gcc-boot0, glibc-final-with-bootstrap-bash, cross-gcc-wrapper,
  static-bash-for-glibc, binutils-final, gcc-final): Change `arguments'
  from a lambda to a list, and use (%current-system) as needed.
  (nix-system->gnu-triplet, boot-triplet): Have the first argument
  default to (%current-system).
* gnu/packages/bootstrap.scm (glibc-dynamic-linker): Have `system'
  default to (%current-system).
  (%bootstrap-gcc): Change `arguments' to a list.
* gnu/packages/gawk.scm (gawk): Likewise.
* gnu/packages/m4.scm (m4): Likewise.
* gnu/packages/make-bootstrap.scm (%glibc-for-bootstrap): Likewise, and
  expect `package-arguments' to return a list.
