# Description:
# ------------
# This file, post-subdir.mk contains following things in
# reference to exec-y and libs-y:
#
# 	Object files name handling, appending destination path.
# 	Assignment of default values, if not defined by Makefile.

### Libraries
# Fix liba-objs-y as follows
#  - include the full path to the directory
#  - change .c with .o
#  - add $(b-output-dir-y)/ as a prefix, so all the objects are in a directory together
#    note that this requires a corresponding stripping of $(b-output-dir-y)/ in the %.o:%.c rule
