51 # To implement this, a symlink tree is built for each library and for each
|
|

52 # multilib subdir.
|

53 #

58 # m68020/

|
|
|
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=.
|
|
|
67 #
|
|
|
68 # Unfortunately, trying to access the libraries in the build tree requires
|
|
|
69 # the user to manually choose which library to use as GCC won't be able to
|
|
|
70 # find the right one. This is viewed as the lesser of two evils.
