Resolve a possible timing issue with "scripts/mysql_fix_privilege_tables_sql.c" in the

Browse Source 
source tarball, this is essential for cross builds, like for NetWare.


scripts/Makefile.am:
  On a fast build machine, both the source (mysql_fix_privilege_tables.sql) 
  and the generated file (mysql_fix_privilege_tables_sql.c) may have identical timestamps
  (granularity is one second only, may be too coarse).
  If that happens, the Makefile rule will fire, and "comp_sql" will be built and called -
  which fails in a cross build, like for NetWare.
  
  Prevent that by sleeping for 5 (five) seconds, this will ensure a time difference.
