So why are you still suppressing the effect of the -small option?

Do you want to suppress the alignment because the data is in the stab
section, or because it's a .stabn / .stabs pseudo-op?
If the answer is the latter, then you can do that by using special
functions to process stabn / stabs, which set sh_no_align_cons before
calling s_stab.
The s_uacons function in tc-sh.c aleady uses sh_no_align_cons to
implement .uaword.
