Add gettext 0.20.1

Two patches from 0.18.8.1 were dropped:
- one changing the declaration of environ is no longer needed, the
corresponding files no longer have this declaration
- one with Woe32 fixes for -O0 may need to be re-added but only after I
find what configuration breaks without it; gettext sources overwent a
massive restructuring so this patch should not be applied without
testing.

+The link error was:
