I found the problem: before, LIB2ADD was passed in from gcc/config via
libgcc.mvars, and added to in t-softfp.  Now the order of the t-*
fragments has been kept the same, with the assignment to LIB2ADD in
c6x/t-elf overriding what has been constructed by t-softfp before.

The following patch did the trick for me, could you give it a try?

Thanks.

	* config/c6x/t-elf (LIB2ADD): Add instead of assigning.
