#
# Generate crunched binaries using crunchgen(1).
#
# General notes:
#
# A number of Make variables are used to generate the crunchgen config file.
#
# CRUNCH_SRCDIRS: lists directories to search for included programs
# CRUNCH_PROGS: lists programs to be included
# CRUNCH_LIBS: libraries to statically link with
# CRUNCH_SHLIBS: libraries to dynamically link with
# CRUNCH_BUILDOPTS: generic build options to be added to every program
# CRUNCH_BUILDTOOLS: lists programs that need build tools built in the
# local architecture.
#
# Special options can be specified for individual programs
# CRUNCH_SRCDIR_${P}: base source directory for program ${P}
# CRUNCH_BUILDOPTS_${P}: additional build options for ${P}
# CRUNCH_ALIAS_${P}: additional names to be used for ${P}
#
# By default, any name appearing in CRUNCH_PROGS or CRUNCH_ALIAS_${P}
# will be used to generate a hard link to the resulting binary.
# Specific links can be suppressed by setting
# CRUNCH_SUPPRESS_LINK_${NAME} to 1.
#
# If CRUNCH_GENERATE_LINKS is set to no, no links will be generated.
