Updated sdcc 3.0.0 compiler added new --use-non-free switch and piklab needs to add the switch to it's default compiler and linker options for new projects using sdcc.

Failing to add the switch to the command line for the compiler and linker results in required files not being found and no easily searchable error message is generated.

There is an upstream project comment here: http://sourceforge.net/projects/piklab/forums/forum/633023/topic/3984411?message=10566426 has a possible fix by adding a compile time option.

A temporary end user work around is to manually add --use-non-free to each project under Project/Project Options/Toolchain/Compiler and /Linker by setting the configuration to Custom, entering --use-non-free in the box and clicking Add.

Reproducible: Always

Steps to Reproduce:
1.Launch Piklab
2.Create a new project with Project/NewProject
3.Enter any name, any Directory and and Device (I used "test" and 16f871)
4.Choose Toolchain Small Device C Compiler
5.Choose Create template source file
6.Enter any valid C code in main()
7.Build with Build/Build Project

Actual Results:  
test.c:3: 23: error: pic16f871.h: No such file or directory
Additionally the following errors occurred but the fix for them is obvious and can wait for upstream to resolve the issue:
test.c:8: warning 197: keyword 'at' is deprecated, use '__at' instead 
test.c:10: warning 197: keyword 'interrupt' is deprecated, use '__interrupt' instead 

Expected Results:  
Message: *** Success *** 

Versions:
$ sdcc --version
SDCC : mcs51/gbz80/z80/ds390/pic16/pic14/TININative/ds400/hc08 3.0.0 #6037 (Apr 13 2011) (Linux)

Piklab 0.12.10 (Using KDE 3.5.10-31.fc15 Fedora)

Setting to medium priority because the errors produced are non-obvious and are not Google friendly.
