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

The only slighty nontrivial change is GLIBC_DYNAMIC_LINKER change:
glibc for alpha uses 'GLIBC_DYNAMIC_LINKER<TAB>"/lib/ld-linux.so.2"'

* gnu/packages/bootstrap.scm (glibc-dynamic-linker): add "/lib/ld-linux.so.2" 
as "alpha-linux" ld.so
* gnu/packages/gcc.scm (gcc-4.7): fix GLIBC_DYNAMIC_LINKER substitution when 
delimiter is a tab
* gnu/packages/linux.scm (system->linux-architecture): add "alpha" arch

I tweaked the commit log and pushed to ‘core-updates’.

Ditto, and I changed the file name to use a hyphen instead of an
underscore.  :-)

Hopefully cross-compilation to alpha-linux-gnu now works in ‘core-updates’?

Thank you!
