Update 64-bit POWER support.

This update brings 64-bit POWER support in line with
other distributions and removes the 32-bit POWER support.
We specify clearly exactly what we support for BE and LE
64-bit POWER.

# We support only 64-bit POWER with the following runtimes:
# 64-bit BE:
# - Power 620 / 970 ISA (default runtime, compatile with POWER4 and newer)
# - Provided for the large number of PowerPC G5 users.
# - IFUNC support provides optimized core routines for POWER6,
# POWER7, and POWER8 transparently (if not using specific runtimes
# below)
# - POWER6 (has power6x symlink to power6, enabled via AT_PLATFORM)
# - Legacy for old systems. Should be deprecated at some point soon.
# - POWER7 (enabled via AT_PLATFORM)
# - Existing deployments.
# - POWER8 (enabled via AT_PLATFORM)
# - Latest generation.
# 64-bit LE:
# - POWER8 LE (default)
# - Latest generation.
#
# No 32-bit POWER support is provided.
#
# There are currently no plans for POWER9 enablement, but as hardware and
# upstream support become available this will be reviewed.
