Linux/ARM: Change default clang version from 3.5 to 3.6 (#4928)

In case of the cross compilation on the ubuntu 14.04 x64
for Linux/ARM, the default version of clang/llvm that is
generated by "#> sudo ./cross/build-rootfs.sh arm" command
is 3.6 without 3.5 as following:

u14.04@x64> ls ./coreclr/cross/rootfs/arm/usr/lib/clang/3.6
include  lib
u14.04@x64> ls ./coreclr/cross/rootfs/arm/usr/lib/llvm-3.6/
bin  build  include  lib  share

Let's keep the clang/llvm version consistently by moving
the default version from 'clang3.5' to 'clang3.6' at build-time
for Linux/ARM.
