# Make looks for obj-files using VPATH only when looking for dependencies
# and applying implicit rules. Though make adapts its automatic variables,
# we cannot use them: The dependencies contain files which have not to be
# linked to the binary. Therefore the foreach searches the obj-files like
# make does, using the VPATH variable.
# Use a surrounding strip call to avoid ugly linebreaks in the commands
# output.

# Dependencies: When we have ld.so, we use MAKEDEP to build our
# library dependencies. If not, we fall back to LIBDEPS, an
# approximation of the correct dependencies for the binary. Note, that
# MAKEDEP will be empty if we dont have ld.so, LIBDEPS will be empty
# if we have ld.so.
