If -# found, the cache variable $ax_cv_gcc_archflag is set to this flag and -# ACTION-SUCCESS is executed; otherwise $ax_cv_gcc_archflag is set to -# "unknown" and ACTION-FAILURE is executed. The default ACTION-SUCCESS is -# to add $ax_cv_gcc_archflag to the end of $CFLAGS. -# -# PORTABLE? should be either [yes] (default) or [no]. In the former case, -# the flag is set to -mtune (or equivalent) so that the architecture is -# only used for tuning, but the instruction set used is still portable. In -# the latter case, the flag is set to -march (or equivalent) so that -# architecture-specific instructions are enabled. -# -# The user can specify --with-gcc-arch=<arch> in order to override the -# macro's choice of architecture, or --without-gcc-arch to disable this. -# -# When cross-compiling, or if $CC is not gcc, then ACTION-FAILURE is -# called unless the user specified --with-gcc-arch manually. -# -# Requires macros: AX_CHECK_COMPILE_FLAG, AX_GCC_X86_CPUID -# -# (The main emphasis here is on recent CPUs, on the principle that doing -# high-performance computing on old hardware is uncommon.) -# -# LICENSE -# -# Copyright (c) 2008 Steven G.
