gnu: gcc: Adjust for "alpha-linux". 

This change allows cross-building packages by just
using --target=alpha-unknown-linux-gnu re2c:

  $ ./pre-inst-env guix build --target=alpha-unknown-linux-gnu re2c
  $ file /gnu/store/p1z9iszzb4ng0vzc535sc2ha33ax24l6-re2c-0.16/bin/re2c
  /gnu/store/p1z9iszzb4ng0vzc535sc2ha33ax24l6-re2c-0.16/bin/re2c: \
      ELF 64-bit LSB executable, Alpha (unofficial), version 1 (SYSV), dynamically linked, \
      interpreter /gnu/store/0z5d6z3hh41w7z5g2g82zlnwgpbj0i1a-glibc-cross-alpha-unknown-linux-gnu-2.24/lib/ld-linux.so.2, \
      for GNU/Linux 3.2.0, not stripped

GCC for alpha uses 'GLIBC_DYNAMIC_LINKER<TAB>"/lib/ld-linux.so.2"'

* gnu/packages/gcc.scm (gcc-4.7)[arguments]: Fix GLIBC_DYNAMIC_LINKER
substitution when delimiter is a tab.
