update-abi does work now for me but if I transfer e.g. the
locale/libBrokenLocale.abilist file for i.86 which is:

GLIBC_2.0 i.86-.*-linux.*
 GLIBC_2.0 A
 __ctype_get_mb_cur_max F

to x86-64 and run update-abi this time as:
$ make update-abi update-abi-config='x86_64-.*-linux.*'

I get a new file:
GLIBC_2.2.5 x86_64-.*-linux.*
 GLIBC_2.2.5 A
 __ctype_get_mb_cur_max F

The config for i.86 is removed.  How should those two get merged
together correctly?

Take your time - and get well again!
