[Buildroot] [PATCH 1/1] Generation of locales: made call to tr more robust

[Thierry Bultel]

When calling 'tr' without quoting braces, bash can make really weird things
if there are existing 'single-letter-named' directories
eg:
thierry at thierry-desktop:~$ echo AAA | tr [A-Z] [a-z] 
aaa
thierry at thierry-desktop:~$ mkdir m
thierry at thierry-desktop:~$ echo AAA | tr [A-Z] [a-z] 
AAA


The (quick) analysis is that the callee (tr) argvs then
contain 'm' thus the translation does not work

Using quotes works around it
tbultel at laois:~/test$ echo AAA | tr '[A-Z]' '[a-z]'
aaa
