It does provide a cross-compiler (info "(guile) Compilation"):

  guix compile --target=mips64el-linux-gnu foo.scm -o foo.go

But note that the interpretation of triplets might defer from that of
GDB.  In particular, for platforms that support several ABIs with
different word sizes, it recognizes some specific triplet
extensions–e.g., “mips64el-linux-gnuabi64” for the N64 ABI on MIPS.  See
<http://git.savannah.gnu.org/cgit/guile.git/tree/module/system/base/target.scm#n76>.
