Subject: [PATCH] erts/emulator: reorder inclued headers paths

If the Perl Compatible Regular Expressions is installed on the
host and the path to the headers is added to the CFLAGS, the
pcre.h from the host is used instead of the one provided by
erlang.

Erlang use an old version of this file which is incompatible
with the upstream one.

Move INCLUDES before CFLAGS to use pcre.h from erlang.
