Right, exclude this architecture.

This probably only happens with certain C libraries only. Check if this
build failure occurs with uClibc or glibc, probably only with uClibc.

Right, exclude this architecture as well.

This is what happens when libatomic_ops is built before gauche. In this
case, gauche tries to use the external libatomic_ops instead of its
internal one.
As I already suggested to fix this, you have two options:
(1) Understand why using the external libatomic_ops doesn't work and
fix it.
(2) Pass a configure option to gauche to force it to use its internal
version of libatomic_ops.
I'd prefer (1), but we can live with (2) if (1) is too complicated.

Two options here:
(1) boehm gc in gauche supports the GC_NO_DLOPEN like the official
boehm gc. In this case, pass -DGC_NO_DLOPEN when
BR2_STATIC_LIBS=y. See bdwgc.mk for an example.
(2) Make gauche depend on !BR2_STATIC_LIBS.
Thanks,
Thomas
