54 # The build tree is layed out as
63 # The nice feature about this arrangement is that inter-library references
64 # in the build tree work without having to care where you are. Note that
65 # inter-library references also work in the source tree because symlink trees
66 # are built when srcdir=.
68 # Unfortunately, trying to access the libraries in the build tree requires

77 # ${srcdir} is not constant.

81 # MULTISRCTOP = number of multilib levels in source tree (+1 if cross)
