--- Comment #15 from Richard Biener <rguenth at gcc dot gnu.org> ---
So I see that

   242: 0000000000000000     0 SECTION LOCAL  DEFAULT  UND=20

and that's indeed broken (UND SECTION?)  but ld complains that the SECTION
type is after the last section entry.  So next up would be to look at the
assembly file the compiler generates for libsass.so.1.0.0.ltrans16.ltrans.o.

The console output shows how it's generated:

 as -v -EL -mips64r2 -mips64r2 -mmsa -mloongson-ext -mloongson-ext
-mloongson-ext2 -mloongson-ext2 -O2 -mabi=3D64 -mabi=3D64 -march=3Dgs464e
-march=3Dgs464e -march=3Dgs464e -mtune=3Dgs464e -mtune=3Dgs464e -mtune=3Dgs=
464e -KPIC -o
libsass.so.1.0.0.ltrans16.ltrans.o libsass.so.1.0.0.ltrans16.s

and the "last" section I see in there is

        .section        .note.GNU-stack,"",@progbits

and I can confirm that GNU as (2.35.1) produces an object with the strange
section (using a cross binutils).  I think that no valid assembly file
should produce that so may I suggest to file a bug at sourceware for an
assembler issue? (just use the libsass.so.1.0.0.ltrans16.s file as testcase)

Maybe there's more mips people around than here.=
