gnu: gcc: Properly set the dynamic linker file name on GNU/Hurd.

* gnu/packages/gcc.scm (gcc-4.7)[arguments]: In 'pre-configure' phase,
match 'GNU_USER_DYNAMIC_LINKER' in addition to 'GLIBC_DYNAMIC_LINKER'.
This fixes GNU/Hurd cross-compilation as reported at
<https://lists.gnu.org/archive/html/guix-devel/2017-01/msg01731.html>.
