Hi Doug
I build both GCC and GLIBC daily but for mips-img-linux-gnu and hard-float the
only prob. I see is ADA fails building one multilib config. I do all langs I'll
give try hard-float mips-mti-linux-gnu.

Created attachment 41513

cut down example via delta

Sorry attachment for the last comment was dropped.

I bisected the failure to r247049 using the cut down
example, compiled via:

$dir/xgcc -B$dir -O2 -msoft-float -mabi=32 delta_1.i -c -std=gnu11
-fgnu89-inline  -O2 -fmerge-all-constants -fno-stack-protector -frounding-math
-g

For this bisect I configured with --disable-multilib.

I'll look into this more tomorrow.
