The asembler files were not built with no-exec.
Comment 1 Andrew Cagney 2006-06-23 17:57:58 UTC 
from notes from jakub:

assembly is by default conservatively assumed to need executable stack
you need either:
1) .section        .note.GNU-stack,"",@progbits somewhere in the assembly
or
2) assemble with -Wa,--noexecstack or 3) link with -Wl,-z,noexecstack
or
3) if it is already linked, you can use the execstack(8) utility
