made erlang binding work with system *installed* dyncall:
- made build use static libraries (used .o files directly)
- removed custom flags for include path and relying on CFLAGS now
- change cc to $(CC)
- readme update with build instructions, etc.

-BUILDING
-========
+BUILD/INSTALLATION
+==================
 
-To build erldc:
+1) make sure dyncall is built and libraries/headers are in include paths or
+   CFLAGS points to them, etc.. Same goes for erlang headers/libs.
+
+2) Build this erlang NIF:
 
-    make DYNCALL_SRC_PATH=../dyncall ERLANG_INST_DIR=/erlang/in/this/dir all
-    sudo make ERLANG_INST_DIR=/erlang/in/this/dir install
+     make
 
-Erlang doesn't use pkg-config, so you must specify ERLANG_INC (and
-ERLANG_INST_DIR at install-time).
+3) To install, pick correct install paths by defining PREFIX (if needed, e.g.
+   for stage dir) and ERLANG_INST_DIR (e.g. /usr/lib64/erlang,
+   /usr/local/lib/erlang, ...):
+
+      make ERLANG_INST_DIR=/erlang/in/this/dir install
+
+Erlang doesn't use pkg-config, so it's up to you to point to set the flags to
+point to correct paths at build and install-time.
 
 The makefile is meant to be portable, at least across *nix.
