'lower-gexp' does not respect 'system' or 'target' keywords |

Hi,
I believe there is an issue with 'lower-gexp'. Running the following
snippet to lower a G-Expression for "i686-linux" yields output that
references store paths built for x86_64. In this case, the Guile
interpreter used is an x86_64 binary.
#+BEGIN_SRC scheme
(define (display-exp exp)
(mlet* %store-monad ((lowered (lower-gexp exp
#:system "i686-linux"
#:target "i686-linux"))
(to-build -> (cons (lowered-gexp-guile lowered)
(lowered-gexp-inputs lowered)))
(_ (built-derivations to-build)))
(return (format #t "~a~%" (lowered-gexp-sexp lowered)))))
(with-store store
(run-with-store store
(display-exp #~(primitive-load #$(switch-system-program %system)))))
#+END_SRC
jakob@Epsilon ~ $ guile ~/test.scm
(primitive-load
/gnu/store/v7v1b7375j9j82dvfycv56v36nv5jq3y-switch-to-system.scm)
jakob@Epsilon ~ $ cat
/gnu/store/v7v1b7375j9j82dvfycv56v36nv5jq3y-switch-to-system.scm
#!/gnu/store/9alic3caqhay3h8mx4iihpmyj6ymqpcx-guile-2.2.4/bin/guile
--no-auto-compile
!#
...
jakob@Epsilon ~ $ file
/gnu/store/9alic3caqhay3h8mx4iihpmyj6ymqpcx-guile-2.2.4/bin/guile
/gnu/store/9alic3caqhay3h8mx4iihpmyj6ymqpcx-guile-2.2.4/bin/guile: ELF 64-bit
LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter
/gnu/store/h90vnqw0nwd0hhm1l5dgxsdrigddfmq4-glibc-2.28/lib/ld-linux-x86-64.so.2,
for GNU/Linux 2.6.32, not stripped
This doesn't seem to be an issue if '%current-system' is parameterized,
as in the following.
#+BEGIN_SRC scheme
(parameterize ((%current-system "i686-linux"))
(with-store store
(run-with-store store
(display-exp #~(primitive-load #$(switch-system-program %system))))))
#+END_SRC

Jakob

Got it now. This is fixed by 2e8cabb8d630a8423e2e5a3bf150c1c0310b945d.
Thanks!
