[M3devel] [cm3] unresolved pthread symbols during bootstrap

[Daniel Alejandro Benavides D.]

Hi,
Looks that you haven't used the SYSTEM_LIBORDER array,
must be "PTHREAD" there in order to really link it.

Maybe this little guide can help. Can have several
omissions, but It works well in (K)ubuntu 6.06 and
6.10
