des.c: constify des tables
DES tables take up a huge amount of space in the .bss and they aren't
even variable. Generate constant tables and put them into des_tables.c
and drop constants and code used to generate them from des.c
This saves ~70KBytes of the .bss and ~3KBytes of the total library size:
text data bss dec hex filename
- 618508 25652 89400 733560 b3178 lib/libuClibc-1.0.42.so
+ 685664 25672 19488 730824 b26c8 lib/libuClibc-1.0.42.so
Modified libc passes the DES validation suite from the uclibc-ng-test.
