# glibc: SFrame does not exist on s390x.
#
# Arch's PKGBUILD passes --enable-sframe, added when x86_64 gained SFrame
# stack tracing. glibc's own configure rejects it outright on this
# architecture:
#
#   configure: error: the architecture doesn't support SFrame
#
# This is not a build-environment problem and no host package fixes it: the
# feature is genuinely absent from s390x. Dropping the flag is what a port
# does -- and it must be dropped surgically, leaving every other configure
# option untouched, so that a future Arch change to this PKGBUILD is not
# silently discarded.
