make.inc.powerpc

# Custom makefile settings for PowerPC (as opposed to Intel x86) architecture.
# Copy this to make.inc to apply.
# It adds a COMP (compiler) make argument, with values COMP=ibm, otherwise GCC.
# By Hugo Brunie, May 2020.
# This makefile is greatly inspired by AMReX (amrex/Tools/GNUMake/comps)
