gnu: commencement: Memoize packages as a function of the system.
Previous, things like 'ld-wrapper-boot0' would be memoized with
(mlambda () …). However, the definition of 'ld-wrapper-boot0' depends
on the result of (%boot0-inputs), which is itself a function
of (%current-system). Thus, if one first calls:
(parameterize ((%current-system "x86_64-linux"))
(ld-wrapper-boot0))
then, in all subsequent calls to 'ld-wrapper-boot0', the value
of (%current-system) would be ignored because the result is already
memoized. Concretely, 'ld-wrapper-boot0' would always have the
dependencies it has on x86_64-linux, even though they are different than
those on armhf-linux, say ("bash-mesboot" vs. "bootstrap-binaries").
Fixes <https://bugs.gnu.org/40482>.
Reported by Marius Bakke <mbakke@fastmail.com>.
* gnu/packages/commencement.scm (define/system-dependent): New macro.
(linux-libre-headers-boot0, hurd-core-headers-boot0, ld-wrapper-boot0)
(gcc-boot0-intermediate-wrapped, gcc-boot0-wrapped, ld-wrapper-boot3):
Define using 'define/system-dependent' instead of 'define' + 'mlambda'.
Adjust users so they no longer look like procedure calls.
* tests/guix-build.sh: Add test.
