ARC port to uClibc
For this port, I would like to give due credit to: - Folks from Codito technologies (Sameer, Amit, Kanika, Ramana,...) who did the very first port - ARC UK from 2007-2009 (Joern, Irfan, Khurram, Phil... - Late Brendan Kehoe (may he RIP) Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
