Second problem, seems to be Suse specific :

/usr/lib/gcc-lib/i486-suse-linux/3.2/../../../../i486-suse-linux/bin/ld: 
cannot find -ltermcap
collect2: ld returned 1 exit status
*** Error code 1

corrected by
cp /usr/lib/termcap/libtermcap.a /usr/lib

------------------------------------------------------------
Third problem :
/usr/cross/bin/nbconfig STATION5

../../../../opencrypto/files.opencrypto:15: duplicate file 
crypto/sha2/sha2.c
../../../../crypto/sha2/files.sha2:5: here is the original definition
*** Stop.

Removed line 15 from opencrypto/files.opencrypto

The kernel works.
