	Yes, as is being discussed on #gcc, changing sections with GCC
__attribute__ is fine, but this code is changing section semantics behind
the compiler's back.  One simply cannot expect that to work.  Linkonce
sections are not just a blackbox string value for GCC to emit.

	Paul Brook suggests adding

CFLAGS-strtoul.c=-fno-section-anchors

to Glibc for all files that explicitly declare symbols in linkonce
sections.  That certainly seems appropriate to me.
