Add basic support for the Blackfin architecture
For uClibc, the name of the Blackfin architecture is 'bfin'. Actually, the naming of the architecture is quite messy: for toolchain tuples and uClibc, it's bfin, but for the kernel, it's blackfin. We've arbitraly choosen to name it "blackfin" in Crosstool-NG. Add Blackfin-related uClibc patch to fix a build failure related to fork() being used in unistd/daemon.c. Yann E. MORIN: Apply the patch to the kernel/linux build script to use 'linux' in the noMMU tuples. See: http://sourceware.org/ml/crossgcc/2010-04/msg00010.html

+Backport UCLIBC_HAS_STUBS config option from the upstream. This option makes uClibc provide fork() stub on NOMMU targets. It's default off.
