Previously, we'd get this error:
$ guix build --target=aarch64-linux-gnu r-minimal -d --no-grafts
guix build: error: path ‘/gnu/store/[^-]+-glibc-[^-]+-static’ is not valid
This is because the sexp would be passed as an input of the surrounding
gexp in 'gnu-cross-build', and thus
"/gnu/store/[^-]+-glibc-[^-]+-static" would be interpreted as a source
file name, as in this example:
scheme@(guix gexp)> #~(foo #$(list 'whatever "/gnu/store/[^-]+-glibc-[^-]+-static"))
$11 = #<gexp (foo #<gexp-input (whatever "/gnu/store/[^-]+-glibc-[^-]+-static"):out>) 7f098badec30>
scheme@(guix gexp)> (gexp-inputs $11)
$12 = (#<gexp-input "/gnu/store/[^-]+-glibc-[^-]+-static":out>)
Fixes <https://issues.guix.gnu.org/59073>.

* guix/build-system/gnu.scm (gnu-cross-build): When PHASES is a pair,
pass it through 'sexp->gexp'.
