When building glibc localedata, gzip is used with -9 option, so timestamp of 
each compressed file is include.

First the timestamp/filename is not required.

Secondly, with timestamp removed, each charmaps gz file and locale-archive have 
always the same md5.
This make paranoid people looking why files are different happier.

Third, with timestamp removed, charmaps files are a few bytes smaller.

Even the oldest gzip I find (gzip-1.2.4) support the -n option.
So use gzip -9n
