# SYNOPSIS
#
#   AX_PROG_HLA([ACTION-IF-NOT-FOUND])
#
# DESCRIPTION
#
#   This macro searches for the HLA assembler and sets the variable "hla" to
#   the name of the application or to "no" if not found. If
#   ACTION-IF-NOT-FOUND is not specified, configure will fail when the
#   program is not found.
#
#   Example:
#
#     AX_PROG_HLA()
#     AX_PROG_HLA([hla_avail="no"])
