Cross-compilation support.
* configure.ac (ASCPP): Remove substituted variable.
(ASCPPPOST, ASCPPFLAGS): New substituted variables.
* lib/Makefile.am (ASCPP, LN_S): Remove unnecessary macro definitions.
(match.$(OBJEXT)): Use CPP, ASCPPFLAGS, ASCPPPOST instead of ASCPP.
* configure.ac: Add test for chown function.
* gzip.c (treat_file) [!HAVE_CHOWN]: Don't call chown.
* gzip.c: Include "timespec.h".  This doesn't fix any bugs, but
it is clearer.
