# Makefile to build libraries common to multiple build targets in the iBoot tree
|
|
#
|
|
# The list of libraries to build is derived from the contents of the file named in LIBLIST, which
|
|
# encodes the library module path, library uniquing tag and build options for the library in the
|
|
# format:
|
|
#
|
|
# <module path>~<uniquing tag>[~<build option>[~<build option>[~...]]]
|
|
#
|
|
# It is assumed that the contents of the LIBLIST file have been uniqued and thus
|
|
# every library target is unique.
