This will not help you that much, since I don't have any libs installed 
using cabal on ARM. Anyway, doing relocations filtering in both stage2 
and libraries directories reveals:

R_ARM_ABS32
R_ARM_CALL
R_ARM_MOVT_ABS
R_ARM_MOVW_ABS_NC
R_ARM_REL32
R_ARM_TARGET1
R_ARM_THM_CALL
R_ARM_THM_JUMP11
R_ARM_THM_JUMP24
R_ARM_THM_MOVT_ABS
R_ARM_THM_MOVW_ABS_NC

Also, yes, my LLVM usually produces ARM code and not Thumb(2) by 
default, whole Ubuntu is based on Thumb2 on the other hand...
