[PATCH 2/3] sha1: silence warning on big endian platforms

[Marc Kleine-Budde]

Silence this warning, which crashes when CONFIG_WERROR is active:

cc1: warnings being treated as errors
libbb/sha1.c: In function 'sha1_end':
libbb/sha1.c:411: error: unused variable 'i'
libbb/sha1.c: In function 'sha512_end':
libbb/sha1.c:446: error: unused variable 'i'
