I guess, it will be more problematic to begin to change the
Makefile.am/.in or configure.ac/.in files in the Debian package, than
just making the custom changes to use Debian pcre-package. If EMBOSS
compiles with a common libpcre-version, upstream should add the
necessary checks for an libpcre installation and prefer this version,
instead of the shipped pcre-version. But for you, this will be overkill
I guess (you know, where the libpcre-header files are installed, so you
don't need such checks).

In short: Change
#include "pcre.h"
to
#include <pcre.h>
and see 'man pcre-config' for the compilation arguments (you only need,
what --libs tells you in the linking step, IIRC).
