Attempt to get rid of -qrtems

[Sebastian Huber]

Hello,

I would like to get rid of the -qrtems command for normal RTEMS 
applications. The difficulty is that the configuration process to build 
GCC with all the target libraries (libatomic, libstdc++, libgomp, etc.) 
relies on some link time tests which use the crt0.o, libc.a and libm.a. 
The attached patch introduces a new -qrtemsstub command line option 
which is enabled during the GCC target library build. In case this 
option is not present, then the standard RTEMS libraries will be used, 
e.g. librtemscpu.a, librtemsbsp.a, libc.a, etc. For backward 
compatibility the -qrtems option is ignored.
