This commit makes the ARC uClibc version handling explicit by adding a
BR2_UCLIBC_VERSION_ARC_GIT option, rather than only relying on the
selected architecture. This is needed in preparation to the
introduction of uClibc-ng support, which also supports the ARC
architecture: so we will now have two uClibc versions capable of
handling ARC.

This commit adds support for a new uClibc version: uClibc-ng
1.0.0. Since its build system is for now exactly the same as the one
of uClibc, we don't create a new package, but instead simply add it as
a new uClibc version.
The only special trick needed is the creation of a symlink to the
program interpreter, due to a mismatch between the program interpreter
file name generated by uClibc-ng and the one used by gcc.
This patch is heavily based on previous work from Waldemar Brodkorb.

I have tested Qemu-Mips (le), Qemu-SH4, Qemu-Sparc and Qemu-ARM.
All worked fine.
You can add
