# 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
