# Upstream broke the aarch64 release asset in 1.28.0: the versioned tarball
# (${MY_PN}-linux-aarch64-${PV}.tgz) was not published, and the unversioned
# ${MY_PN}-linux-aarch64.zip that replaced it is a 358K archive carrying only
# _manifest/spdx_2.2/ SBOM files -- no lib/ and no include/.  There is no
# usable arm64 binary for this version, so restore ~arm64 once upstream ships
# a complete aarch64 asset again.

# Verified with `readelf -d` on 1.27.1 (both x64 and aarch64): the DT_NEEDED
# set is libdl, librt, libpthread, libstdc++, libm, libgcc_s, libc, ld-linux.
# Everything but libstdc++/libgcc_s comes from libc, so only gcc is named here.
# Note these are glibc-linked binaries and cannot work against musl; ::gentoo
# handles that class of package with a musl profile mask rather than an
# RDEPEND on sys-libs/glibc, which would be unsolvable on musl profiles.
