New -mcrt option

[rolsen74]

This is an enhancement request

I have written a new c-library for AmigaOS4.

Currently gcc is hardcoded to clib2 or newlib ... I like too have a new option ralib for -mcrt .. that way I can avoid overwritting the clib2 install.

Currently there is a

sdk:clib2
sdk:newlib
sdk:local/common
sdk:local/clib2/include
sdk:local/clib2/lib
sdk:local/newlib/include
sdk:local/newlib/lib

I like to add

sdk:ralib/include
sdk:ralib/lib
sdk:local/ralib/include
sdk:local/ralib/lib

When linking a program I mimic clib2 and have these 3 objects

crt0.o
crtbegin.o
crtend.o

crt0.o is really not used its just have the assembler instruction 'blr' witch just return. so its not needed.

All the objects and include files can be obtained here

Those files a released under a BSD license so you can redistrubute them if you want.
