# libtool: drop the 32-bit multilib split package.
#
# Arch builds libtool as (libtool lib32-libltdl). The build() step that
# compiles the 32-bit half is already guarded by [[ $CARCH = x86_64 ]] and
# never runs here -- but prepare() copies the source tree to src/libtool32
# UNCONDITIONALLY, and package_lib32-libltdl() then packages a tree that was
# never built:
#
#   cp: cannot create regular file '.../src/libtool32/libtool/.git...'
#
# lib32 is i686-on-x86_64 multilib. It has no meaning on s390x, where no
# 32-bit userspace is shipped and lib32-glibc does not exist. Removed rather
# than repaired: the artefact itself is architecture-specific.
