Well, it's to be expected since dpkg-gensymbols is blacklisting
them:
see scripts/Dpkg/Shlibs/SymbolFile.pm:
# Many armel-specific symbols
$blacklist{"__aeabi_$_"} = 1 foreach (qw(cdcmpeq cdcmple cdrcmple cfcmpeq
cfcmple cfrcmple d2f d2iz d2lz d2uiz d2ulz dadd dcmpeq dcmpge dcmpgt
dcmple dcmplt dcmpun ddiv dmul dneg drsub dsub f2d f2iz f2lz f2uiz f2ulz
fadd fcmpeq fcmpge fcmpgt fcmple fcmplt fcmpun fdiv fmul fneg frsub fsub
i2d i2f idiv idivmod l2d l2f lasr lcmp ldivmod llsl llsr lmul ui2d ui2f
uidiv uidivmod ul2d ul2f ulcmp uldivmod unwind_cpp_pr0 unwind_cpp_pr1
unwind_cpp_pr2 uread4 uread8 uwrite4 uwrite8));
If some of them are no longer "internal machinery" and no longer present in
random libraries, then we ought to de-blacklist them.
See #462318 for the bug that requested them to be blacklisted.
