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.
