I have build the library two times w/wo patch to compare the .so sizes:

(ls -l build/glibc/libc.so)

size without Cyrillic translit
17172016 bytes

size with Cyrillic translit (patch applied)
17180208 bytes

the difference is 8192 bytes

 From what I gathered if the Cyrillic translit table goes into the C 
locale it doesn't have to be included into other locales. So it is only 
included once with a ~8K size increase.

If another locale wants to have its own different transit table that 
would then go on top but towards its own size budget.
