Fix build on BSD systems
I tested FreeBSD, DragonflyBSD, NetBSD and OpenBSD and the endian
macros weren't necessary (and in fact caused errors) on all of them.
Because OpenBSD ships with an ancient GCC that doesn't support the
checked addition/multiplication builtins, the build there would fail
unless built with CC=cc or CC=clang. I changed configure.ac to prefer
cc over gcc, so that the distribution's compiler preference is
respected. (The default is [gcc cc]). I had to move AC_PROG_CC above
LT_INIT because otherwise LT_INIT would run AC_PROG_CC first, and we
wouldn't have a chance to use non-default parameters.
