Pic32 toolchain support

I don't program pic32 (but STM32) but for toolchain just download gcc and 
build mips-none-eabi target.

building is quite messy but after this it works.

Personally i DO NOT use any libraries and other manufacturer supplied 
shit, instruction consist of all addresses so it's better to just write 
and read data from peripherals directly.

For STM32 i have my own "crt0" (actually 192 bytes of interrupt tables 
and 20 bytes of startup assembly). For PIC32 make your own.

As for programming - there are free software but for linux. you may have 
to modify sources a bit but it should not be a problem.
