build: use pkg-config (if available) to configure libpcre
Problem reported by Mike Frysinger in: http://bugs.gnu.org/16757 * bootstrap.conf (bootstrap_post_import_hook): Copy pkg-config's pkg.m4. * configure.ac: Invoke PKG_PROG_PKG_CONFIG. * m4/pcre.m4 (gl_FUNC_PCRE): Rewrite to use pkg-config if available, and to test that pcre_compile can be linked to. * src/Makefile.am (AM_CFLAGS): Add PCRE_CFLAGS. (grep_LDADD): Add PCRE_LIBS. * src/pcresearch.c: Simply include <pcre.h> if HAVE_LIBPCRE, since 'configure' arranges for the appropriate -I option now.
