[bug#74416] [PATCH] gnu: petsc: Remove arch version from uname output.

[Lars Bilke <lars.bilke@ufz.de>]

Enables reproducible building on machines with have a different
arch-suffix in uname output, e.g.:

Machine·characteristics:·Linux-x.x.x-arch1-1-x86_64-with-glibc2.39

vs.

Machine·characteristics:·Linux-x.x.x-arch2-1-x86_64-with-glibc2.39

Will become

Machine·characteristics:·Linux-x.x.x-archx-x-x86_64-with-glibc2.39
