8 # of each subdirectory, eg: newlib, libio, etc.) until the right way to do

13 # user select which libraries s/he really wants.
15 # FIXME: Multilib is currently disabled by default for everything other than
16 # newlib. It is up to each target to turn on multilib support for the other
17 # libraries as desired.
19 # FIXME: It would be better if we could use the --print-multi-lib switch to
20 # gcc to get the list of directories to build, but at this point the compiler
23 # Only do this if --enable-multilib.
