Subject: [PATCH] crc32.c: cleanup unused variables warning

Variables t4, t5, t6 and t7 are only used when CRC_LE_BITS != 32. This cleans
the following compilation warnings:

lib/crc32.c: In function 'crc32_body':
lib/crc32.c:77:55: warning: unused variable 't7'
lib/crc32.c:77:41: warning: unused variable 't6'
lib/crc32.c:77:27: warning: unused variable 't5'
lib/crc32.c:77:13: warning: unused variable 't4'
