Merge pull request #94 from gartnerd/master

These changes allow to compile RetroBSD on a Linux Mint host with 32bit libraries installed.
The simulator in "tools/virtualmips/pic32" seems to work fine.

* removed the -Wall compiler flag (hopefully this will be temporary) from makefile recipes to prevent errors from stopping compilation. It mostly fails on printf type functions because of string size conflicts.
* added the "-m32" flag so that compilation and linking produced 32bit executables. I'm not sure is if this is strictly necessary.
* copied Makefile.kconfig to Makefile.kconfigpic32. The files in the pic32 directory compile after making this change
* modified the code in config.h to explicitly tag those function that are externally defined. This is required by newer versions of gcc
* hacked config.y so that the lexer/compiler stopped complaining.
* commented out the "compp" variable in main.c because of size mismatch errors. It doesn't seem to be used for anything.
* added a system header file to tools/kconfig/mkswapconf.c so that the compiler could find included functions
