Subject: [PATCH] Don't override CC, CFLAGS, and LDFLAGS.

The bzip2 build is quite simple and does not use autotools for
configuration. The simple Makefile provided overrides CC, CFLAGS, and
LDFLAGS which means it cannot be cross compiled or fuzzed. Use the user
supplied flags to allow build modification.
