build: honor CFLAGS & friends from environment
Debian build scripts pass CFLAGS in the environment.
However, this is ignored by Sparse's Makefile since 'CFLAGS'
is unconditionaly initialized.
Fix this by initializing CFLAGS to its default value using '?='.
Do the same for PKG_CONFIG, DESTDIR, BINDIR, MANDIR and
CHECKER_FLAGS.
Note: It's useless to try to do the same for CC, LD & AR since
they're builtin variables so '?= ...' is a no-op for them
(unless make is called with -R).
Note: This makes sparse native builds reproducible for Debian.
