libgloss: Remove duplicate definition of environ 

Environ is defined in libgloss and libc:
 - libgloss/or1k/syscalls.c
 - libc/stdlib/environ.c

When linking we sometimes get errors:
or1k-elf-g++ test.o -mnewlib -mboard=or1ksim -lm -o  test
/opt/shorne/software/or1k/lib/gcc/or1k-elf/5.3.0/../../../../or1k-elf/lib/libor1k.a(syscalls.o):(.data+0x0):
multiple definition of `environ'
/opt/shorne/software/or1k/lib/gcc/or1k-elf/5.3.0/../../../../or1k-elf/lib/libc.a(lib_a-environ.o):(.data+0x0):
first defined here
collect2: error: ld returned 1 exit status

This doesnt happen after the fix. Basic things build fine too.
