Order without my patch:

$ LC_ALL=lv_LV.UTF-8 ls
Ʒ  a   Aa  æ   Āb  c  D  i   Y   yb  Īb  ĵa  L  ņ   ra  Ŗa  Sa  š   T   Zb  ža

Order with my patch:

bash-4.4# LC_ALL=lv_LV.UTF-8 ls 
a  Ā   ab  Æ  č  H  y	Īa  īb	Ĵ   ķ  M  Ø   ŗ   Ŗb  Sb  šb  Z   zb  Ža  ʒa
A  aa  Ab  c  Č  i  Y	ya  Īb	ĵa  Ķ  ņ  ra  Ŗ   S   š   Šb  ȥ   Zb  žb  Ʒa
Ã¥  Aa  āb  C  D  I  ia	Ya  yb	Ä´a  L  Å
  Ra  ŗa  sa  Š   t   Ȥ   ž   Žb  ʒb
Ã
  āa  Āb  ç  ģ  ī  Ia	ib  Yb	ĵb  ļ  O  rb  Ŗa  Sa  ša  T   za  Ž   ʒ   Ʒb
ā  Āa  æ   Ç  Ģ  Ī  īa	Ib  ĵ	Ĵb  Ļ  ø  Rb  ŗb  sb  Ša  z   Za  ža  Ʒ
bash-4.4#

So I think this patch fixes the problems reported in the bug
by using

copy "iso14651_t1"

and then add the same collation tailoring for Latvian as in CLDR
instead of implementing the whole collation for Latvian from
scratch as it is currently done in glibc.
