# Attempt to fix any "-m elf64ppc" linker checks in configure and
# libtool.m4 files.
#
# This script is meant to run silently as part of rpm's %configure
# macro. It either fixes the problem, or we silently ignore it, in
# which case it is up to the package maintainer to add support for
# ppc64le.
# Our two attempts at fixing the problem.

# There are two variants in RHEL7 so far. The first version, handled
# with $PATCH1, currently handles all but 3 packages. The $PATCH2
# version handles the remnant.
