Hello Guix! On the 'core-updates' branch, running 'guix build -d' fails on some cross-derivations (notably anything that depends on NSPR, but there may be others).
Somehow both TARGET and SYSTEM ends up #false. Any ideas to what is going on? --8<---------------cut here---------------start------------->8--- $ ./pre-inst-env guix build --target=aarch64-linux-gnu nspr -d Backtrace: In guix/monads.scm: 471:9 19 (_ _) In guix/packages.scm: 1553:7 18 (_ _) In guix/store.scm: 1996:13 17 (_ #<store-connection 256.99 7f5816372e60>) In guix/packages.scm: 1878:37 16 (_) 1798:39 15 (bag->derivation #<<bag> name: "ld-wrapper-aarch64-linux-gnu-0" system: #f target: #f build-inputs: () host-inputs: (("binutils" #<package binutils-cross-aarch64-linux-gnu@2.38 gnu/packages/cross-base.scm:69 7f58054e12c0>) ("guile" #<package guile@3.0.8 guix/build-system/gnu.scm:145 7f5804e65420>) ("bash" #<package bash@5.1.16 gnu/packages/bash.scm:131 7f5804bae210>) ("wrapper" "…> …) 1291:4 14 (bag-transitive-inputs _) 1074:23 13 (transitive-inputs _) 1415:36 12 (propagated-inputs _) In srfi/srfi-1.scm: 586:29 11 (map1 (("libunistring" #<package libunistring@1.0 gnu/packages/bootstrap.scm:297 7f58054e1000>) ("bdw-gc" #<package libgc@8.0.6 gnu/packages/bootstrap.scm:297 7f58054e5f20>))) 586:17 10 (map1 (("bdw-gc" #<package libgc@8.0.6 gnu/packages/bootstrap.scm:297 7f58054e5f20>))) In guix/packages.scm: 1370:20 9 (rewrite ("bdw-gc" #<package libgc@8.0.6 gnu/packages/bootstrap.scm:297 7f58054e5f20>)) In guix/memoization.scm: 101:0 8 (_ #<hash-table 7f5804e64be0 2/31> #<package libgc@8.0.6 gnu/packages/bootstrap.scm:297 7f58054e5f20> _) In guix/packages.scm: 1384:13 7 (_) In guix/build-system/gnu.scm: 157:33 6 (cut? _) In gnu/packages/bdw-gc.scm: 61:15 5 (arguments #<package libgc@8.0.6 gnu/packages/bootstrap.scm:297 7f58054e5f20>) In guix/utils.scm: 672:7 4 (target-hurd? _) In unknown file: 3 (string-suffix?
