arc: libgloss: Add support of EM SDP board
These specs files are introduced for EM SDP board:
* emsdp1.1.specs - EM SDP 1.1, everything in ICCM/DCCM memory
* emsdp1.1_ram.specs - EM SDP 1.1, startup code in ICCM
memory and everything else in RAM
* emsdp1.2.specs - EM SDP 1.2, everything in ICCM/DCCM memory
* emsdp1.2_ram.specs - EM SDP 1.2, startup code in ICCM
memory and everything else in RAM
An example of building an application:
$ arc-elf32-gcc -mcpu=em -specs=emsdp1.1_ram.specs main.c -o main
