Generation of locales: made call to tr more robust and added LOWERCASE macro

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