Creating Linux SOs (shared libs) appropriately

[GoogleCodeExporter]

Accordingly to Linux Documentation, mongoose does not create its shared 
properly.

Referring to what is stated at the following link on this matter, the attached 
patch provides a way to create mongoose's SO accordingly for Linux:

Cheers!

Sorry, I forgot to mention the method used for issuing Make, though.

i.e. to build mongoose-3.1 on a Linux Box:

$ VERSION=3.1; make VER="$VERSION" SOVER="${VERSION%.?}" CFLAGS="-lssl -lcrypto 
-DNO_SSL_DL" linux

It will produce:
$ ls
bindings  libmongoose.so.3.1  main.c    mongoose    mongoose.c  test
examples  LICENSE             Makefile  mongoose.1  mongoose.h  win32

ELF dumping the SO:

$ readelf -d libmongoose.so.3.1

Pushed 79cdb77.
I've made Makefile configurable MONGOOSE_LIB_SUFFIX for the library suffix, if 
one chooses to use it.
