Compiling for macOS

New compile scripts for ngspice executable and shared library,
using gcc-11 from Homebrew.
All relevant options are included (readline, openmp, X11 graphics etc.)

+#     See https://github.com/orlp/dev-on-windows/wiki/Installing-GCC--&-MSYS2
+# start compiling with
+# './compile_min_shared.sh' for release or './compile_min_shared.sh d'
+# for debug version of shared ngspice
+
+# Options:
+# --adms and --enable-adms will install extra HICUM, EKV and MEXTRAM models via the 
+# adms interface.
+# Please see http://ngspice.sourceforge.net/admshowto.html for more info on adms.
+# CIDER, XSPICE, and OpenMP may be selected at will.
+# --disable-debug will give O2 optimization (versus O0 for debug) and removes all debugging info.
+# To obtain a 32 bit executable, replace -m64 by -m32 ./configure lines.
+
+# Add (optionally) --enable-relpath to avoid absolute paths when searching for code models.
+# It might be necessary to uncomment and run ./autogen.sh .
